Two rats are not two small hamsters with better manners. They climb, they forage, they build deep nesting burrows, and they need real floor space to do any of it, which is why picking a rat cage for two rats is the first decision most new owners get wrong. A pet store hamster cage with 1 inch bars will not hold a pair of adults, and an aquarium that looks roomy from the outside can quietly cause respiratory trouble.
The cage we would buy first is the MidWest Critter Nation Double Unit Small Animal Cage. It is all metal, it measures 36 x 24 x 63 inches across two full levels, and its half-inch horizontal wire spacing contains even small adults. It also holds a 4.6 star average across more than six thousand ratings, the deepest review history of anything we looked at, which matters when you plan to keep this purchase for years.
We spent weeks working through specs, owner reviews and long-running forum threads on best rat cages for two rats to build this list. Every cage below was scored on the same five things: usable cubic feet, bar spacing at the bar level, whether the floors are solid, how easy the cage is to reach into, and what owners say after living with it. All measurements come from the manufacturer listings, and the cubic foot figures are our arithmetic on those published dimensions rather than marketing claims.
One note before we start. Rats are social animals and a pair is genuinely better than a single rat, so every cage here is sized for two from the start. If you already own a small animal enclosure, read the guinea pig cage guide first, because the sizing logic is shared and the floor material rule is exactly the same.
Essential Cage Requirements for Two Rats
Four rules decide whether a cage works for a pair of rats. Nearly every bad purchase we read about in reviews failed one of them, and nearly every good one passed all four.
Space: 2.5 cubic feet per rat is the widely cited minimum, so 5 cubic feet total for two. Experienced keepers push that to 5 cubic feet per rat, meaning 10 cubic feet or more, and that is the number we used when judging these cages.
Bar spacing: 1/2 inch (1.27 cm, 12.7 mm) or narrower for juveniles and small females, and 3/8 inch (about 0.95 cm, 9.5 mm) for babies. Anything at a full inch is a hamster cage, not a rat cage.
Flooring: no bare wire mesh underfoot. Standing on wire causes bumblefoot, a painful bacterial infection of the feet, so you want solid platforms, and every wire level or ramp covered with fleece, a mat or an old towel.
Ventilation: wire on all sides, open top or top vents. Aquariums and plastic bin cages trap ammonia from urine, and ammonia is a direct cause of respiratory disease in rats.

1. Critter Nation Double Unit – Best Overall for Two Rats
Critter Nation by MidWest Double Unit Small Animal Cage
36 x 24 x 63 inches
About 31.5 cubic feet
1/2 inch wire spacing
44 lb
Pros
- Two genuine full-width floors instead of ledges
- All metal so there is nothing plastic to chew
- Half-inch spacing holds small adults
- Doors open all the way for handling and cleaning
- Bars under the shelves take hammocks
Cons
- Assembly takes one to one and a half hours with two people
- Occasional bent pegs or crooked door panels from the factory
- Large footprint is awkward to move through a doorway
This is the cage the rat community keeps coming back to, and after reading thousands of owner reviews it is the one we kept putting back at the top of the list. Two full levels, each with a full-width resting shelf rather than a narrow ledge, means a fall from the upper level lands on a solid surface instead of bare wire. That single design decision is what separates it from almost every cheaper cage here.
The 1/2 inch horizontal wire spacing is the number most people search for, and it does contain rats. Owners running small females and juveniles report no escapes, and the wire is heavy gauge in a gray quartz hammertone finish that has held up through years of daily chewing and cage-washing.
Two things make cleaning bearable: full-width double doors that swing open to the cage’s entire width, and two removable base pans you can lift out rather than slide sideways. Owners also mention the swing-up locking ramp, which lets you section off one level during a clean or temporarily separate the animals.
The honest drawback is assembly. Owners consistently put it at one to one and a half hours, with two people and a rubber mallet. If you are buying this as a first pet purchase, plan an afternoon rather than an evening. At 36 x 24 x 63 inches and 44 pounds, you will also want a second person to help move it into position.
What you should check before ordering the Double Unit
Measure your intended spot first, including the door swing and the space needed to slide the base pans out. The cage needs a wide footprint, and owners who bought it during a house move report it does not fit through a narrow doorway without tipping.
Second, decide now whether you want one big cage or an expandable system. Because this unit exists as a single, an add-on and a double, many owners buy one section now and add the second later as the rats grow. Decide which arrangement you want before assembly day, since combining them later is far easier than splitting them.
Where the Double Unit falls short
Two recurring complaints are worth knowing about. A minority of owners received units with bent pegs, scratched or crooked door panels, or a cracked tray, and while manufacturer support is described as responsive, that is still a box you are opening with two people.
Second, the shelf system is height-adjustable but the shelves themselves do not cover the entire footprint edge to edge, so falls remain possible from the top level. If you have an older rat with weaker legs, add fleece-covered perches and a small ramp at each level rather than assuming the platform alone is enough.
2. You & Me Rat Manor – Best Four-Level Starter Habitat
You & Me by Petco Rat Manor Habitat 16.5″ L X 22.5″ W X 32″ H
16.5 x 22.5 x 32 inches
About 6.9 cubic feet
3/8 inch wire mesh
17.5 lb
Pros
- Four levels give plenty of vertical climbing
- 3/8 inch mesh contains babies and small females
- Deep metal base cuts bedding scatter
- Powder-coated welded wire wipes clean easily
- Tool-light interlocking assembly
Cons
- Smallest footprint in this roundup
- Wire mesh levels still need fleece covers
This is the cage most search results currently name as a starter pick, and it earns that reputation with tight 3/8 inch wire, four levels, three ladders and a deep metal base. The 3/8 inch mesh is narrower than anything else in this roundup, which makes it the safest choice here if you are buying before your rats are fully grown.
Weighing it against the rest, the honest weakness is footprint. At 16.5 x 22.5 inches it gives two rats good vertical room but a narrow base, and owners report that a full-size exercise wheel eats a big share of the ground floor. It works, but two adult rats will use it more like a climbing tower than a play space.
One thing to know before you order: the listing dimensions conflict. The product title states 16.5 inches long by 22.5 inches wide by 32 inches high, while the specification block lists 16.5 x 22.5 x 16.5 inches. Measure the shipped unit when it arrives, because it makes a real difference to how much ground space you are giving two rats.
The deep metal base is genuinely useful. Owners cite it as the reason bedding scatter around the habitat is minimal, and the powder-coated finish means a damp cloth handles urine splash without soaking in.
Is the Rat Manor big enough for a pair of adult rats?
On total volume, yes: roughly 6.9 cubic feet is above the 5 cubic foot minimum for two, and the four levels give climbing structure that smaller flat cages lack. The catch is that this is a tall, narrow layout rather than a wide one.
If your rats are still babies, the tight mesh is the standout advantage and you will not have to think about escapes. If you are buying for full-grown adults, take a look at the wider cages further down this list and see whether the footprint fits your room better.
Where the Rat Manor falls short
The four levels are wire mesh, so every one needs a fleece cover, mat or old towel laid on top, and that is an ongoing chore. Owners who skip it report sore feet on their rats within weeks, which is the early stage of bumblefoot.
At 17.5 pounds it is light to move, but light also means the joints flex a little when two rats push against a door. Expect to tighten clips after the first month rather than assuming the frame stays rigid forever.
3. Kaytee My First Home Multi-Level – Best Value Multi-Level
Kaytee My First Home Multi-Level Exotics Habitat for Pet Chinchillas, Rats, Degus, Sugar Gliders and Other Exotic Small Animals
30.5 x 18 x 30 inches
About 9.5 cubic feet
1/2 inch wire spacing
16.5 lb
Pros
- Wide 30.5 inch base suits two rats
- 1/2 inch spacing with chew-proof locks
- Deep base limits bedding spill
- Light enough to reposition alone
- Over 900 ratings to judge it by
Cons
- Listed dimensions conflict between the spec and feature blocks
- Space between levels catches spilled food and droppings
- Multi-level design means two clean-up jobs
This one is the balance pick in the roundup. At 30.5 x 18 x 30 inches it is wider than most multi-level cages at this size, which matters more for two rats than the extra vertical inches you get from a tower design. Half-inch wire, chew-proof wire and locks, and a deep base that keeps bedding inside.
The reviews describe a functional rather than exciting cage, and that is exactly why we like it. Nearly a thousand ratings sit behind it, with owners consistently naming the tight spacing, the deep base and the multiple levels as the reasons it works. It is light enough at 16.5 pounds that one person can pull it out for a clean.
Be aware that the specification block and the feature bullets give different measurements. The feature text says 30.5 x 18 x 30 inches while the spec fields list something closer to 30.5 x 8.5 x 18.5 inches. This is common with multi-level habitats where sellers measure the pack rather than the assembled cage, so measure after assembly.
Cleanup is the part that catches people. Because the levels are stacked with gaps between them, food and waste drop from one tier to the next, and owners report that a full clean means working top to bottom rather than lifting one tray.
When the Kaytee Multi-Level beats a double-decker tower
Choose this shape when floor area is your priority. Two rats do far more ground-level foraging, wheel running and side-by-side resting than climbing, and the 30.5 inch length gives them room to run nose to tail in a straight line.
It also suits rentals where ceiling height is the limit. A cage that is wide but under three feet tall fits under a standard piece of furniture, which a 60-plus inch tower will not.
Where it falls short
There is no storage shelf underneath, unlike several picks in this roundup, so the cage occupies its whole footprint with nowhere to stash bedding and toys. Owners who keep extra supplies add a slim shelf beside it.
Solid floors are not the strength here either. Whatever the levels are made from, treat them as wire until you have laid fleece over every surface, because the gap between tiers is exactly where an unprotected foot gets caught.
4. Homey Pet 3-Tier Cage – Best for Rolling Cleanups
Homey Pet Rat Cage, Small Animal Cage for Ferret, Chinchilla, Guinea Pig
25 x 17 x 38 inches
About 9.3 cubic feet
0.65 inch wire spacing
20 lb
Pros
- Four 360 degree lockable casters with brakes
- Detachable grates and a 1 inch removable tray
- Splash guard keeps bedding and debris contained
- Two-finger door lock resists clever rats
- Rust-resistant thickened wire
Cons
- Debris lodges in the gap beside the urine guard
- Assembly needs patience because similar panels are easy to misplace
- 0.65 inch wire spacing is wider than the half-inch models
The reason this cage made our list is the wheels. Four lockable casters with a brake system mean you can roll the whole unit to a patio or driveway and hose it out, which is the fastest deep clean available for any wire cage. Owners who switch to this from a plastic tray model rarely go back.
It is also a genuinely tall, open design at 25 x 17 x 38 inches, with plenty of bars for hanging hammocks and toys. That open interior matters because rats climb for the sake of climbing, and vertical structure is cheap enrichment.
The 0.65 inch wire spacing is the catch. It is wider than the half-inch on most picks here, and it is wider than we would want if your rats are juveniles or small females. For two full-grown adult males or adult females of average size it is fine, but check your rats against the gap before committing.
The detachable plastic floor grates and the 1 inch removable tray make routine spot cleans quick, and the splash guard on the bottom does keep bedding in. The problem is the same splash guard when you go deeper: hay, fur and food lodge in the channel between the cage wall and the guard, and owners report needing to partially disassemble the base for a proper wash.
Is this cage right for a home with hard floors?
Yes, and that is where the casters pay off. A cage on wheels also means you are not lifting 20 pounds through a doorway every cleaning day, which owners with back problems specifically call out as the deciding factor.
Lock the casters before you reach in. A rolling cage that moves when a rat jumps against the door is a stress event for the rat and a real pinch risk for your fingers.
Where the Homey Pet falls short
Assembly is the main complaint. Owners describe side clips that are fiddly to align and panels that look identical, so read the parts list carefully and sort the hardware into groups before you start.
A minority of reviewers also feel the wire is not heavy enough for rats that chew constantly. If your pair is known chewers, an all-metal wrought iron cage like one of the Mcage models further down is a better long-term buy.
5. Mcage 3-Level Collapsible Cage – BUDGET PICK
3-Levels Portable Rat Sugar Glider Mouse Small Animal Critter Metal Cage
24 x 16 x 24 inches
About 5.3 cubic feet
3/8 inch bar spacing
11.75 lb
Pros
- Lowest entry cost in the roundup
- 3/8 inch spacing is the tightest here and holds babies
- Folds flat for storage between uses
- Carry handles double as travel handles
- No tools needed and the tray pulls straight out
Cons
- Bent bars and platforms often arrive out of the box
- Thin flexible wire leaves uneven gaps at doors and corners
- A tunnel under the bottom tray is a crawl-out risk
This is the budget pick and it clears the minimum size line for two adult rats at about 5.3 cubic feet. The 3/8 inch cross bar spacing is the tightest in the roundup, and at under twelve pounds it folds flat and carries by its top handles, which makes it useful as a hospital or quarantine cage as well as a home.
Roughly 1,900 ratings sit behind it, and the feedback splits cleanly. Supporters call it a perfectly serviceable starter cage for two adults, citing the tool-free setup, the pull-out washable tray and its survival of heavy gnawing on an epoxy-coated finish.
The detractors focus on build quality, and these are worth taking seriously. Bars and platforms arrive bent more often than owners would like, the wire is thin enough to flex, and that flex leaves uneven gaps around the doors and corners that some owners close with zip ties or small clips.
There is also a crawl-out risk. The bottom tray sits under the frame with a tunnel-shaped gap, and a determined rat can work into that space. Check it yourself once the cage is set up, and block it with a solid base panel or a close-fitting fleece mat.
When this budget cage makes sense
Buy this one if your rats are adults, your budget is tight, and you want a second small cage anyway. That last use is real: experienced keepers keep a folding cage for quarantine, for a sick rat at the vet, and for the days you deep clean the main habitat.
Because it folds to a flat panel, it also works as temporary housing during a move or a renovation, which is a situation most owners do not plan for until it happens.
Where it falls short
Do not bed it heavily. Owners repeatedly report bedding falling through the wire levels and collecting under the tray across the floor, so plan on spot cleaning daily or accept a permanent layer of substrate underneath.
At 24 x 16 inches the interior is cramped for a full-size exercise wheel and for anything beyond two rats. Owners also recommend it as a temporary or first cage, and pointing heavy chewers toward heavier wrought iron models instead.
6. Mcage Deluxe Double Unit – Best All-Metal Double
Deluxe Double Unit Two Full Story Small Animal Critter Home Rolling Cage
20.5 x 20 x 45 inches
About 10.7 cubic feet
1/2 inch wire spacing
33 lb
Pros
- Full middle floor rather than partial ledges
- All metal and chew-free with nothing plastic to destroy
- Two large 21 x 15 inch hinged front doors
- Hammock water bottle and food bowl included
- Four rolling casters plus a bottom storage shelf
Cons
- Instructions often belong to a different cage variant
- Bottom tray does not lock into place
- Ramps described as flimsy and flex under weight
For a double-decker layout at a mid price point, this is the pick. It measures 20.5 x 20 x 45 inches on the rolling stand, giving about 10.7 cubic feet, which is double the minimum for a pair. The full middle floor is the detail that matters most, and it is a real floor rather than a perch.
Everything is wrought iron, which reviewers treat as the deciding factor for rats that chew. There is no plastic base to gnaw through and no plastic shelf to strip, and the paw-safe fabric covers on the platforms and ramps are a thoughtful addition for foot comfort.
Two large hinged front doors measuring 21 x 15 inches open wide enough that you can reach the back corners, and the included hammock with cage hook, water bottle and food bowl mean the cage is usable the day it is assembled rather than after a separate shopping trip.
The build is where this one loses points. Owners report instructions and diagrams that belong to a different cage variant, ramps that flex under a rat’s weight, and a bottom tray that does not latch securely into place. A few units also arrive with deformed bars or a panel from the wrong side.
Is this the right cage for rats that chew everything?
Yes, and it is the main reason we included it. Owners with heavy chewers rate the all-metal construction as the feature that finally ended a cycle of chewed plastic trays and stripped shelves, and the 1/2 inch spacing keeps adult rats in without modification.
Pair it with solid perches you add yourself if your rats ignore the supplied platforms. Fleece-covered flat pieces give them a genuine rest surface without leaving wire underfoot.
Where it falls short
Watch the tray. Because it does not lock into place and the latch can be worked from the inside, check it during the first week and again whenever you hear scratching under the cage.
The rating here is the lowest in the roundup, driven mostly by assembly documentation and out-of-box part quality rather than by the design itself. Inspect every bar and panel the day it arrives.
7. Mcage X-Large 4-Level – Best Vertical Climb
Huge X-Large Wrought Iron 4-Level Chew-Proof Tight 1/2-inch Wire Spacing Ferret Chinchilla Sugar Glider Rats Mices Rabbit Squirrel Hamster Cage with Detachable Rolling Stand
32 x 19 x 67.5 inches
About 23.8 cubic feet
1/2 inch wire spacing
Pros
- Five usable levels in a 67.5 inch tall frame
- All metal chew-proof platforms and ramps
- Detachable rolling stand with a storage shelf
- Two of the four casters are lockable
- Pull-out metal grate and washable tray
Cons
- Tall narrow footprint is awkward in smaller rooms
- Assembly of this size typically needs more than one person
- Weight is not listed
- Bar spacing is half inch so babies need a separate nursery setup
This is the vertical option: 32 x 19 x 67.5 inches, roughly 23.8 cubic feet, with five usable tiers. If your rats are climbers and you have the ceiling height for it, that much usable vertical structure is hard to find anywhere near this price band.
The detachable rolling stand is the feature owners praise most. A cage this tall would be unmanageable on its own, and separating the stand from the cage body means two people can each carry one piece. Two of the four heavy-duty casters lock, so it stays put once positioned.
The all-metal chew-proof platforms and ramps are a genuine plus, and the pull-out metal grate with a washable plastic tray keeps the cleaning routine straightforward. A storage shelf underneath keeps bedding and food out of the enclosure itself.
What you give up is width. At 19 inches across, the ground-level run is modest for two adults, so most of the activity happens vertically. That is fine for athletic rats and less ideal if you want a pair that can nose-to-tail sprint on a flat floor.
Does a tall cage mean more falls?
It can, and this is where the half-inch spacing and metal ramps earn their keep. Rats are agile climbers, but a 67.5 inch drop onto a hard floor is a real injury risk, so add fleece-covered rest platforms at more than one level rather than spacing them too far apart.
The 1/2 inch wire spacing also means this is not a nursery cage. If you are expecting babies, you will want a separate smaller cage with tighter spacing, and you will want to know the sex of every animal before that point.
Where it falls short
Measure your ceiling and your doorways before you commit. Owners with smaller rooms report the height is awkward, and the assembled unit needs more than one person to put together.
Product weight is not published for this model, which matters more than usual on something this size and this tall. If you plan to move it rather than wheel it, check the shipped weight first.
8. HABUTWAY 2-Tier Rolling Cage – Best With a Side Cleaning Door
HABUTWAY 40”H Large Metal Rolling Ferrets Cage, 2-Tiers Small Animal Cages, Cage for Rats/Chinchillas, 0.5” Bar Spacing for Ferret,Small Animal Cage w/Removable Ramp & Platform
36.5 x 23 x 39 inches
About 18.9 cubic feet
0.5 inch wire spacing
42 lb
Pros
- Roomy two-tier layout with generous headroom
- Solder-jointed rust-resistant bars resist breaking
- Side door plus pull-out waterproof tray for cleaning
- Metal storage shelf underneath
- Removable flannel ramp sleeve protects footpads
Cons
- Heavy at just over 42 pounds before accessories
- Smaller review base than the established models
- Two levels means less vertical variety than a tower
The side door is what separates this cage. Most wire habitats force you to reach through the front opening, whereas a side access door plus a pull-out waterproof tray means you can clean the far wall without trying to fish a rag in behind a hiding rat. For two rats that both like to hide, that saves a lot of frustration.
It is also one of the larger footprints in the roundup at 36.5 x 23 x 39 inches, about 18.9 cubic feet, with 0.5 inch spacing. The manufacturer describes a current revision using high-strength rust-resistant metal with solder-jointed bars, which is a direct answer to the bent-bar complaints that hit cheaper cages.
Two details we would highlight for two-rat households. The removable flannel ramp sleeve protects footpads on the wire ramp, which is one of the most common sore spots, and the door lock is designed so a small animal cannot operate it from the inside.
Four universal wheels make the heavy frame movable, and the metal open shelf underneath holds toys and treats away from the animals. All hardware, numbered parts, tools and step-by-step instructions are included, which is more than several rivals manage.
How do you move a cage over 40 pounds?
You do not pick it up. Roll it on the four universal wheels to wherever you are cleaning, then use the pull-out tray and side door rather than trying to reach into the far corners.
Keep it on hard flooring or a smooth surface. Wheels that are fine on tile drag badly on carpet, and dragging a loaded cage across carpet is how casters and frames crack.
Where it falls short
Weight is the honest drawback. At just over 42 pounds before you add bedding, bottles, hides or toys, this is a two-person job if you ever need to lift it rather than roll it.
The review base is also the smallest in this roundup, so there is less long-term feedback about how the solder joints and coating hold up over years. The 0.5 inch spacing is fine for adults but not for a litter of babies.
9. Prolee 40 Inch Wooden Habitat – Best for Deep Bedding
Prolee Hamster Cage Chewproof Wooden 40 Inch Guinea Pig Cages Mice and Rat Habitat Openable Top with Acrylic Sheets Solid Built
40 x 20 x 20 inches
About 9.3 cubic feet
Solid floor
28.3 lb
Pros
- Rates 4.5 stars with 77 percent five-star reviews
- Polyester-coated panels rats do not gnaw through
- One large solid floor that supports deep bedding and burrowing
- Acrylic windows give a clear unobstructed view
- Top vents help with air circulation and odour
Cons
- Reduced visibility compared with wire on all sides
- Interior decoration and accessories are not included
- Solid-sided design is less easy to reach into than a wire cage
This is the only non-wire cage in the roundup, and it rates 4.5 stars with 77 percent five-star reviews. The reason owners love it is the floor. A single uninterrupted 40 inch solid surface lets you pour in real bedding depth, and digging is behaviour rats need rather than a bonus.
The panels are high-density natural wood with a polyester coating on both sides for waterproofing, corrosion resistance and chew resistance. For a species that chews everything, a coated panel is a much better bet than raw wood, which absorbs urine and cannot be fully cleaned.
Transparent acrylic window panels give you a clear view of the animals, and the liftable roof with its own viewing window means you can check on a hiding pair without lifting the whole front. Vents on the top handle air circulation and odour reduction.
An acrylic sheet is included as the cage floor, and the removable front acrylic panel plus the waterproof coating make cleaning far easier than with raw wood. A lock is included for optional installation, though the manufacturer describes the cage as safe without it.
Why does bedding depth matter for rats?
Because digging, burrowing and nesting are core behaviours, and a wire floor denies all three. Rats on solid flooring with six inches of substrate will build and re-bury nests; rats on wire will pace and chew. The health argument matters too, since constant standing on wire is what causes bumblefoot.
A solid 40 inch floor also means you can split the interior into zones with hides and tunnels without worrying about whether an object is stable on a slope.
Where it falls short
You give up the all-around visibility and the reach-in access of a wire cage. Two rats that hide are harder to check on, and handling means opening the front rather than lifting a door.
Interior decoration and accessories are sold separately, so the effective cost is higher than the habitat alone. Four sizes are available from 24 to 48 inches in length, so confirm you are ordering the 40 inch version.
10. Kaytee My First Home Habitat – Best Lightweight Starter
Kaytee My First Home Habitat for Pet Rats
25.5 x 12.5 x 14 inches
About 2.6 cubic feet
1/2 inch wire spacing
5.3 lb
Pros
- Half-inch wire spacing with chew-proof locks
- Deep base limits bedding and litter spill
- Solid plastic shelves and ramps are comfortable and wipe clean
- Weighs just over 5 pounds so it moves easily
- A good temporary or single-rat setup
Cons
- Only about 2.6 cubic feet
- falls short of the two-rat minimum
- 12.5 inch width means two rats cannot pass comfortably
- Listed dimensions differ between spec and feature blocks
We are including this one as a reference point rather than a two-rat recommendation. At 25.5 x 12.5 x 14 inches it works out to roughly 2.6 cubic feet, which is about half the recommended space for a pair. Owners generally describe it as a starter or single-rat cage where two animals feel cramped.
What it does well is real, though. Half-inch wire spacing with chew-proof wire and locks, a deep base that stops bedding spilling, solid plastic shelves and ramps that are comfortable and easy to wipe, and at just over five pounds it is the easiest cage here to move.
Buying it for two rats is the mistake we most often see discussed in reviews. Owners point out that at 12.5 inches wide, two adult rats cannot pass each other comfortably on one level, and the vertical space of 14 inches does not make up for the lost floor area.
Where it genuinely earns a place is as a temporary home. It works well for a single rat during quarantine, for a newly introduced pair during the first few days of bonding, or as a hospital cage while the main habitat is being cleaned.
Should you buy this cage for two baby rats?
Only if you plan to move up before they reach full size. The half-inch spacing will contain them and the plastic shelves will not injure their feet, but the 2.6 cubic feet is not enough long term and you will end up buying twice.
If your rats are babies, a better short-term answer is a cage with 3/8 inch spacing, such as the Mcage collapsible or the Rat Manor, paired with a proper adult cage on the way.
Where it falls short
The width is the core limitation. Multi-level layout helps a little, but you cannot make a 12.5 inch footprint feel like a pair space.
Measurements also conflict between the specification block and the feature bullets, so check the assembled size. And since the shelves are plastic, they are eventually chew targets no matter how well they wipe clean.
How to Choose a Rat Cage for Two Rats
How big does a cage need to be for two rats?
The widely cited minimum is 2.5 cubic feet per rat, which gives 5 cubic feet for a pair, and experienced keepers recommend double that at 5 cubic feet per rat, or 10 cubic feet total. Rat community consensus on the minimum floor footprint is around 80 x 50 cm with a minimum height of 60 cm, which is about 31 x 20 inches at 24 inches tall.
To do the math yourself, take the published length, width and height in inches, multiply all three, then divide by 1728. The Critter Nation Double Unit at 36 x 24 x 63 inches works out to about 31.5 cubic feet. The Mcage collapsible at 24 x 16 x 24 inches gives about 5.3 cubic feet, which is the bare minimum line.
Remember these are outer envelope figures. The interior is smaller once you account for trays, shelves and the frame, so treat any cage that only just reaches the minimum as a minimum.
Bar spacing by rat age: inches, cm and mm
Bar spacing is the one specification where a mistake is fatal, because a determined adult rat will fit through gaps that look generous in a photo. Match the gap to the smallest rat in the group, not the average.
Babies: 1/2 inch (1.27 cm, 12.7 mm) or narrower. 3/8 inch (0.95 cm, 9.5 mm) is the safe choice, and this roundup’s two 3/8 inch cages are the ones to buy if babies are coming.
Juveniles and small females: 1/2 inch (1.27 cm, 12.7 mm) is the ceiling. Owners of small females report this contains them reliably, and the majority of picks in this roundup sit here.
Full-grown adults: up to 1 inch (2.54 cm, 25.4 mm) is often cited, but many experienced keepers still use half inch because a thinner rat or a juvenile you add later will not.
For comparison, mice need tighter bars than rats, typically a quarter inch or less, because a mouse fits through gaps an adult rat cannot. If you are housing rats, a half inch floor is the number to work from.
Full-width floors beat ledges and wire grates
This is the single biggest quality difference between cages in this roundup. A full-width floor covers the entire level edge to edge, so a fall lands on a solid surface. A ledge covers maybe a third of the level and leaves the rest as wire. A wire grate has no floor at all.
The Critter Nation Double Unit and the Mcage Deluxe Double Unit have genuine full-width floors. Several cheaper models are built from wire shelves, and owners of those cages are strongly advised to remove the shelves and add solid perches, then cover whatever remains with fleece, mats or old towels.
Fleece matters. Fleece is the standard liner because it is soft, warm, washable and, unlike some bedding pads, not something a rat will chew into harmful pieces. Be careful with anything that degrades into fluff if gnawed.
Doors, trays and wheels: what makes cleaning bearable
Reach-in access decides how often you will actually clean. Full-width double doors, like those on the Critter Nation, let you reach every corner without dismantling anything. A single small front door forces you to reach past a rat that is actively avoiding you, which means dirty corners and bitten fingers.
The HABUTWAY goes further with a side access door, which is the closest thing to a hatch you will find here. Wide front doors at 21 x 15 inches on the Mcage Deluxe are also strong for a cage at this tier.
Trays vary more than most listings suggest. Look for a pull-out washable tray with some depth, and check whether it latches. The Mcage Deluxe tray does not lock, and the Mcage collapsible leaves a crawl-out tunnel beneath it. Wheels matter more than expected too: four lockable casters let you roll a heavy cage to a hose, which is the fastest deep clean there is.
Tall vs long: which shape suits two rats
Floor footprint matters more than total height. Rats are ground animals first and climbers second, so a cage that is wide and moderately tall beats a narrow tower of the same volume. The Kaytee Multi-Level at 30.5 inches long and the HABUTWAY at 36.5 x 23 inches both fit that brief; the Mcage X-Large at 19 inches wide does not.
That said, tall-and-wide with intermediate floors is the ideal combination, because it gives ground-level running room and vertical structure at the same time. Just avoid the single tall level with a couple of ledges near the top. That layout gives you the fall risk of height with none of the usable space, and it is the design experienced keepers warn against most.
The same footprint-versus-height logic shows up in every large-bird housing decision too, so if you ever keep parrots as well, our best parrot cages ranking works through the tall-and-wide layouts in much more detail.
Rat Cage Setups to Avoid and the Safety Rules That Matter
Most rat cage problems are not about the brand. They are about four specific design choices that appear again and again in owner complaints, and each one has a named health consequence.
Bare wire mesh floors: the most repeated complaint in rat communities about affordable cages. Constant standing on wire causes bumblefoot, a painful bacterial infection of the feet that can require medical treatment. Remove the grate where possible, and cover anything left with fleece.
Aquariums and plastic bin cages: both trap ammonia from urine. Ammonia buildup is a direct driver of respiratory disease, which is why wire on all sides with open top or top vents is part of the core requirements.
Raw wood enclosures: wood absorbs urine, holds odour and cannot be fully sanitised. Coated or sealed panels are acceptable, which is why the coated wooden habitat in this roundup rates well. Untreated wood is not.
Thick plastic bases and shelves: rats chew straight through them. Owners frequently upgrade to an all-metal cage for exactly this reason, and the fully metal models here avoid the problem entirely.
If you already own a cage that is too small or has wire floors, a retrofit can buy you time. Remove or cover the wire grate, add solid full-width perches and fleece covers on every level and ramp, zip-tie any gaps around doors and corners, and increase bedding depth in a solid section. That will not turn an undersized cage into an adequate one, but it removes the most common causes of foot and respiratory problems while you save for a bigger home.
One more practical note: keep a small secondary cage or carrier. Experienced keepers use one for quarantine when bringing a new rat home, for a sick animal, for vet trips, and for the days the main cage needs a full clean. The folding Mcage in this roundup works well for all four, and one experienced keeper has kept a small second habitat for quarantine and temporary housing for sixteen years.
Frequently Asked Questions
What are the best cages for two rats?
For most households the Critter Nation Double Unit is the strongest all-round choice: two genuine full-width floors, all metal construction with nothing plastic to chew, and half-inch wire spacing that holds small adults. If you need something cheaper, the Mcage 3-Level Collapsible hits the 5 cubic foot minimum and has the tightest spacing in the roundup at 3/8 inch. If your rats are still babies, prioritize bar spacing over everything else.
What is the best size cage for 2 rats?
The widely cited minimum is 2.5 cubic feet per rat, so 5 cubic feet total for a pair, and experienced keepers recommend 5 cubic feet per rat, or 10 cubic feet or more. Rat community consensus puts the minimum floor footprint at about 80 x 50 cm with a height of at least 60 cm, which is roughly 31 x 20 by 24 inches. Compute cubic feet by multiplying length by width by height in inches and dividing by 1728.
How far apart should rat cage bars be?
Half an inch, which is 1.27 cm or 12.7 mm, is the standard for juveniles and small females. Babies need half an inch or narrower, and 3/8 inch, about 0.95 cm or 9.5 mm, is the safest choice. Adults technically cope with up to 1 inch, or 2.54 cm, but many keepers stay at half inch so a thinner rat or a later addition cannot escape. Match the gap to the smallest rat, not the average.
Do rats prefer tall or long cages?
Floor footprint matters more than total height. Rats are ground animals first, so a wide, moderately tall cage beats a narrow tower of the same volume. Tall-and-wide with intermediate floors is ideal because it gives ground-level running room plus vertical structure. Avoid a single tall level with only a few ledges near the top, since that creates fall risk without adding usable space.
Is 2 rats better than 1?
Yes. Rats are social animals and keeping one alone causes measurable stress, so a companion is strongly recommended. That is a direct argument for buying a cage sized for two from the start rather than starting with a single-rat habitat and upgrading later. It also means choosing bar spacing for the smaller, younger rat if you are buying before both are fully grown.
How to bond two rats?
Buy the main cage first, and keep a small separate carrier or secondary cage. New rats should be quarantined for about two weeks in the small cage before any introduction. Bonding then runs through short, supervised sessions in the small space, followed by free-roaming time together outside the cage, and only then shared housing in the main enclosure. Never put a new rat straight into an established pair’s territory.
Do rats need a wire or solid floor?
Solid, or covered. Bare wire mesh is the most repeated complaint about affordable cages because constant standing on it causes bumblefoot, a painful bacterial infection of the feet. Best options are full-width solid platforms, then covering every remaining wire level and ramp with fleece, a mat or an old towel. A solid floor also supports deep bedding so rats can dig, burrow and nest, which is natural behaviour they are denied on wire.
The Best Rat Cages for Two Rats in 2026: Final Verdict
The Critter Nation Double Unit is the best rat cage for two rats in 2026 for one simple reason: it has real full-width floors on both levels instead of ledges, and nothing in it is plastic. It also carries the deepest review history of anything we evaluated, which is worth something when your rats will live in it for years.
For a tighter budget, the Mcage 3-Level Collapsible meets the 5 cubic foot minimum and has the tightest bar spacing in the group, but treat it as a starter setup rather than a permanent home. For the best balance of size and price with a wide base, the Kaytee My First Home Multi-Level is hard to argue with at just over 900 ratings and a 30.5 inch length.
Whichever you choose, check bar spacing against your smallest rat before you order, cover every wire surface with fleece, and keep a small folding carrier for quarantine and vet trips.
