The best rat cages for two rats are multi-level metal enclosures with solid floors, half-inch bar spacing and at least 8 cubic feet of usable space. Those four criteria decide nearly everything else, and they are the filter we used to pick the ten cages below.
Rats are burrowing, climbing animals with sensitive lungs. A cage that is too small, floored in bare wire, or barred too wide will cause stress, paw damage or escapes, no matter how nice it looks in a photo. Getting the enclosure right first is cheaper than replacing it a year later.
We spent weeks comparing specifications, customer photos and owner complaints across ten popular cages, then sorted them by how they hold up for a bonded pair. Every cage here is written up with its real measurements, the situations it suits, and the complaints reviewers actually raise. Updated for 2026.

Top 3 Picks for Two Rats
The Critter Nation Double Unit takes the top slot because it is the only cage in this group with both full levels, half-inch horizontal spacing and more than 6,000 owner reviews behind it. The Prevue 485 offers more raw volume and a storage stand, but its 7/8-inch bars rule out babies. The Kaytee My First Home is the pick if you want half-inch bars in a simpler, rat-specific frame.

Only three of these ten have half-inch or narrower bars, so the answer to which cage fits babies is short: the Critter Nation Double Unit, the Kaytee My First Home and the Mcage collapsible. Everything else is built for adult-sized animals.
1. Critter Nation Double Unit – Best Overall Rat Cage for Two Rats
- Two genuine full levels rather than corner ledges
- Half-inch horizontal spacing contains even juvenile rats
- Full-width double doors swing open for cleaning
- Splits into two standalone enclosures for separation
- Over 6000 owner reviews
- Assembly needs two people and a rubber mallet
- 44 pounds and a large footprint in a small room
- Stiff and noisy door latches
This is the cage most rat owners mean when they say the gold standard. It measures 36 x 24 x 63 inches and offers two full levels rather than a floor with corner shelves, which matters because rats use vertical space as seriously as floor space.
Half-inch horizontal wire is the detail that separates it from most cages here. Reviews repeatedly note that not even small rats squeeze through, and the shelves carry bars for hammocks at several heights.
Two full-width plastic base pans pull out for cleaning, and the double doors open completely, so scrubbing the interior takes minutes. The swing-up locking ramp splits the habitat into two areas.
The cost is effort and room. Reviewers describe assembly as a two-person job with tight peg tolerances, most using a rubber mallet, and at 44 pounds the footprint dominates a small room.
Who this cage suits
Right pick for a bonded pair that arrived as babies, since half-inch bars mean you never move up as they grow. Owners report three rats still leave room to spare.
The split design handles quarantine and illness isolation as well as it handles a third rat.
Where it falls short
Measure the room first. Leave clearance for the doors to swing and for you to walk past, or cleaning becomes a daily fight.
Factory defects come up in reviews, such as bent pegs or a cracked tray. MidWest replaces shipping damage quickly, so inspect the box before building.
2. Prevue 485 Feisty Ferret Home – Roomy Adult Pair Cage
Prevue Pet Products 485 Feisty Ferret Home with Stand, Black Hammertone Small
- Deep interior for adult-sized animals
- Two large doors that can be closed to make two spaces
- Caster wheels plus a storage stand for supplies
- Platforms
- grille and tray all removable
- Seven-eighth inch bars are too wide for babies
- Bulky footprint with a separate stand
- Listed for ferrets rather than rats
The most reviewed enclosure in this group, at roughly 7,200 ratings averaging 4.5 stars. It measures 31 by 20 inches and stands 41.5 inches tall, or 54 on the included stand.
Two large hinged doors are the standout. They are escape-proof for the animals this cage is built for, and either one can be closed off to create two separate spaces.
Ramps, shelves and a hammock come included, and the platforms, grille and bottom tray all lift out for cleaning. The stand underneath stores bedding, hides and treats.
The catch is the wire. Seven-eighth inch suits ferrets and similarly sized animals, not rats. A juvenile can exploit that gap, so it is the wrong cage to buy before your rats reach adult size.
Who this cage suits
Adult pairs who want volume without a 63-inch frame. The 31-inch length gives long floor runs, which is the axis rats use most when they come out.
The dual-door partition doubles as a quarantine space when you bring home a new rat from a rescue or breeder.
Where it falls short
Bar spacing rules it out for babies and small females. Buying before your rats mature means choosing one of the half-inch options instead.
The separate stand makes it a two-piece unit to position, so measure both footprints before ordering.
3. Kaytee My First Home – Half-Inch Bars for Babies
- Designed specifically for rats and similar exotics
- Half-inch wire spacing keeps small rats contained
- Chew-proof wires and locks suit heavy gnawing
- Deep base helps contain bedding
- Disassembles for cleaning
- Lower and shallower than the tall multi-level cages
- Published dimensions differ between the bullet points and the spec section
Kaytee built this habitat with rats, degus, chinchillas and sugar gliders in mind, and the half-inch wire is why it belongs on a two-rat list. Many hamster and ferret cages here are wider than they should be for small rodents.
At 30.5 by 18 by 30 inches it has a compact footprint, which suits a first pair in an apartment. The manufacturer lists it for ages one month and up.
Chew-proof locks and wires matter with rats, because everything in reach gets tested by teeth. The deep base keeps bedding contained, and the habitat comes apart for cleaning.
The trade-off is height. Thirty inches is modest beside a 52-inch enclosure, so adult rats use it as a ground-level space with a climb rather than a full multi-level habitat.
Who this cage suits
First-time owners adopting young rats feel confident here, because half-inch bars are the standard the RSPCA and the wider rat community quote. You skip the awkward stage of discovering your cage was too wide.
It also works as the second cage in a two-cage setup: quarantine, a hospital crate, or an overnight spot during a deep clean.
Where it falls short
Volume is the limit. It works for two adults, but experienced keepers aim higher for long-term housing.
Published dimensions are listed two different ways, so measure the assembled unit rather than planning a shelf from the listing.
4. Mcage 3-Level Collapsible – Narrowest Bars at 3/8 Inch
3-Levels Portable Rat Sugar Glider Mouse Small Animal Critter Metal Cage
- Narrowest bars in this roundup
- Collapses flat with carry handles for transport
- Tool-free assembly most owners finish quickly
- All-metal wire holds up to determined chewing
- Pull-out washable tray
- Bars and shelves can arrive bent and flex
- Bottom grate cannot be removed without opening a tunnel
- Cramped once a wheel is added
At three-eighth inch, this Mcage has the narrowest bar spacing in the group. Nothing smaller is needed, and owners of pairs report juveniles stay contained.
It measures 24 by 16 by 24 inches across three levels, with wire shelves, ladders and two front doors measuring 6.5 by 11.5 inches. Two top carry handles and a folding frame mean it travels.
All-metal construction is the real strength. Reviewers describe paint barely marked after months of gnawing, and the pull-out washable tray makes cleaning quick. Setup needs no tools.
Sentiment on safety is mixed. Some rat owners needed zip ties for bent bars that arrived out of square, while others needed no modifications at all. Inspect the frame before trusting it.
Who this cage suits
Anyone with small, young or slippery rats, since three-eighth inch closes off gaps half-inch leaves open. It doubles as a vet carrier.
The folding frame solves another problem: when you deep-clean the main habitat, move the pair here for a few hours.
Where it falls short
The floor grate is the biggest issue. Pulling it out opens a tunnel beneath the tray, and leaving it in blocks burrowing. Cover it rather than remove it.
Interior space is tight once you add a wheel, a hide and an igloo. It works as a secondary cage more comfortably than as the only home for two adults.
5. Yaheetech 52-Inch 6-Level – Best Value Vertical Space
Yaheetech 52-inch Ferret Cage 6 Level Metal Rat Cage with 3 Front Doors/Feeder/Wheels Small Animal Cage for Ferret/Chinchilla/Bunny/Rabbit/Squirrel, Black
- Six tiers of vertical space for climbing and enrichment
- Three latched front doors give access at different levels
- Powder-coated steel resists wear and water
- Four 360-degree casters roll and lock
- Slide-out tray under a grate floor
- Bar spacing wider than rat-specific cages
- 52-inch height needs vertical clearance
- Grate floor needs covering for paw health
The vertical-space pick, with six tiers inside a powder-coated steel frame. More than 5,200 owners have rated it at 4.3 stars, and the height is what appeals to people who want climbing room rather than floor area.
Three latched front doors serve separate level groups, so you can reach the top without dismantling anything. That matters in a cage this tall.
Corrugated ramps reduce slipping, and rounded corners protect hands during handling. The slide-out tray sits beneath a metal grate, so cleaning means pulling one tray out.
Two details deserve attention. Bar spacing is wider than rat-specific cages, making this adult-only, and the grate floor should be covered so rats are not standing on wire all day.
Who this cage suits
Adult pairs in a room with high ceilings. Six tiers plus a covered grate gives climbing routes a two-level cage cannot offer.
It also suits owners who rotate enrichment, with room for hammocks and platforms at different heights without everything stacking on one shelf.
Where it falls short
Bar spacing decides it for many buyers. If your rats are juveniles or you may adopt young ones, choose half-inch instead and skip this one.
A 52-inch frame with casters will not fit under a low shelf or a sloping ceiling, so measure the vertical space first.
6. Homey Pet Rat Cage – Budget Pick for Rat Owners
Homey Pet Rat Cage, Small Animal Cage for Ferret, Chinchilla, Guinea Pig
- Marketed for fancy and Dumbo rats specifically
- Anti-spill guards contain bedding and debris
- Four lockable 360-degree wheels
- Fully detachable frame for deep cleaning
- Non-slip textured ramp and wide platform
- Side clips are fiddly and can loosen
- Debris collects in the gap by the urine guard
- Hard-to-reach inner corners
- Lowest rating among the rat-specific options here
One of the few here built and marketed for rats rather than ferrets or chinchillas, and the listing names fancy and Dumbo rats directly. It measures 25 by 17 by 38 inches across three tiers with 0.65-inch wire.
For a pair of adults it reads roomy, and owners describe it as good value for the space. Four 360-degree lockable wheels let you roll it out of a draft or across the room to clean.
The anti-spill splash guard at the base is a thoughtful addition. Bedding and debris stay inside, and detachable paw-friendly plastic grates filter waste toward the one-inch removable tray with rounded corners.
Cleaning is where reviews get critical. Debris gathers in the gap between the frame and the urine guard, and some owners report loosening side clamps and adding zip ties.
Who this cage suits
Adult pairs on a tighter budget who still want a rat-appropriate layout with a splash guard, wide platform and casters.
Because 0.65 inch is wider than half inch, this suits full-grown animals only. Check the spacing against your rats first.
Where it falls short
Assembly is awkward, with side clips that are difficult to slide flush, and those clips are the part owners reinforce later. Budget extra time.
It carries the lowest rating among the rat-specific cages here at 4.1 stars, with a noticeable share of one-star reviews. That reflects assembly and cleaning friction rather than safety failures.
7. PawHut 4-Tier Rolling Cage – Smallest Footprint
PawHut Metal Small Animal Cage, 4-Tiers Rolling Big Ferret Cage, Gray
- Tall four-tier layout for climbing
- Hammock included at the top
- Four smooth-rolling wheels
- Pull-out bottom tray and two doors
- Open wire design gives good ventilation
- Square footprint uses floor space less efficiently
- Wide bars suit adults rather than babies
- Listed for ferrets
- chinchillas and sugar gliders
When floor area is the problem, footprint matters more than height. The PawHut measures 20.5 inches on each side against a 44.75-inch height, and that narrow square base slides into corners where a 31-inch-long cage will not.
Around 2,080 owners rate it at 4.1 stars, and it ranks in the top ten for small animal cages. The four-tier layout and included top hammock give a real climbing route.
Two doors and a pull-out tray make feeding and cleaning straightforward, and the open steel wire ventilates well so you can see every level without crouching.
The trade-off is that a square footprint wastes floor space. Rats run in straight lines, and 20.5 inches of width is a shorter lap than the 24 to 31 inches wider cages give you. Wide bars also rule out juveniles.
Who this cage suits
A pair of adults in a bedroom, dorm room or flat where a wider rectangular cage blocks a walkway. Height gives vertical interest while the base stays under 21 inches each way.
A compact footprint also makes a second cage for quarantine or cleaning days much easier to place.
Where it falls short
Bar spacing again. The listing positions this model for ferrets, chinchillas, kittens and sugar gliders, so verify the gap against your rats.
At 26.4 pounds it is not a light lift despite the wheels, and the square base gives less usable floor area per cubic foot than any rectangular cage here.
8. Polar Aurora 59-Inch – Tallest Climbable Frame
- Tallest frame in this group at nearly 59 inches
- Thick 13mm square pipe with hammer-pattern finish
- Five platforms at varied heights plus a top hammock
- Detachable deep base tray
- Four wheels with two brakes
- Vertical wire spacing near one inch is wide for rats
- Needs real vertical clearance in the room
- Listing states it is not for hamsters or mice
The tallest enclosure here at 58.6 inches, with a 31.5 by 20.5 inch base that gives real climbing height without a huge floor footprint. It averages 4.3 stars from just over 1,000 owners.
Construction is heavier than most cages in this bracket. The main body uses 13mm square pipe at 0.8mm thickness, with a hammer-pattern finish for wear and rust resistance and latches for safety.
Five platforms sit at different heights, linked by ramps lined with blue flannel so climbing is not slippery, with a hammock at the top. The deep base tray detaches for cleaning, and four wheels include two brakes.
The wire spacing is the problem. Horizontal spacing is listed at 3.94 inch with vertical wire at 0.98 inch, and the manufacturer states the cage is not for hamsters or mice.
Who this cage suits
Adult rats in a room with tall ceilings who want maximum climbable height. The build quality and braking wheels suit a cage that stays put once positioned.
The deep detachable tray suits bedding depth, and the r/RATS guidance asks for around four inches of tray depth minimum for a pair.
Where it falls short
Near one-inch vertical spacing is too generous for a pair. If your rats are young or you may adopt a small female, choose a half-inch cage instead.
Plan the room before it arrives, because a 58.6-inch frame is not easy to reposition once loaded with bedding and platforms.
9. SUPER DEAL 4-Tier Cage – Most Included Extras
SUPER DEAL 37.2 Inches Metal Ferret Cage Chinchilla 4 Tiers Small Animal Cage with 3 Ladders/ 2 Front Doors/Food Bowl/Water Bottle/Slide Out Trays/Swivel Casters,Black
- Chew-proof and scratch-proof metal that holds up to gnawing
- Removable grille and slide-out tray simplify cleaning
- Four swivel casters that lock in place
- Three ladders
- bowl
- water bottle and shelves included
- Folds flat for storage
- Outer bar spacing of 1.1 inch is the widest here
- Overall height limits headroom
- Listing advises checking bar spacing before buying
The least shopping-heavy start for a first pair. Three ladders, shelves, a food bowl, a water bottle and four levels of space are all in the box.
It offers 25 by 17 by 35 inches of living space in a square-tube frame with strong metal wire and a rust- and rot-resistant black finish. Reviewers highlight the low cost and how well the metal withstands chewing.
The removable grille and slide-out tray make cleaning simple, and the metal and hard rubber casters let you move the cage and lock it in place. Replacement platforms and ramps are sold separately.
Be clear-eyed about the bars. Outer spacing is listed at 1.1 inch with 0.47 inch grille spacing, and the listing itself advises checking spacing before buying.
Who this cage suits
First-time owners with two adult rats who want one purchase to cover housing and the basic accessories. Rounded corners make it safe around small hands during handling.
It folds flat for storage, which matters if the cage moves between rooms with the seasons.
Where it falls short
The 1.1-inch outer spacing is the widest in this roundup and the reason it sits lower despite the included extras. Never put a juvenile pair in this cage.
Height is modest at roughly 37 inches overall, so climbing room is limited even with four tiers.
10. HABUTWAY 50-Inch 5-Tier – Side-Access Cleaning
- Side opening in addition to front doors for deep cleaning
- Waterproof pull-out tray wipes clean easily
- Soldered bar joints resist bending
- Five platforms plus flannel ramps and a top hammock
- Front and side doors with four wheels
- two braked
- Plastic tray and platforms described as flimsy
- Instructions confusing and hardware holes sometimes uncut
- Weak wheel legs and latches
- 0.9-inch wire spacing is wide for rats
The easiest of the tall cages to scrub out. Alongside the front doors it has a side opening, which owners single out as the plus for reaching corners in a cage that stands 50.4 inches tall and weighs 35.7 pounds.
Inside are five platforms at different heights, blue flannel-lined ramps between them and a hammock at the top. The interior measures 31.5 by 20.5 inches, a long floor area for a pair.
The waterproof pull-out tray wipes clean without absorbing urine, the difference between a ten-minute clean and a twenty-minute one. Soldered bar joints give it a sturdy feel in the hand.
The complaints are consistent enough to plan around. Owners call the tray and plastic platforms flimsy and easy to chew through, find the instructions confusing, and report weak wheel legs and latches.
Who this cage suits
Adult pairs who prioritise long floor space and easy cleaning over fine bar spacing. Owners regularly call it good value, and the waterproof tray is a real advantage with rats.
The side opening also helps during vet recovery, when you want to reach into one section without lifting an animal through a small door.
Where it falls short
At 0.9-inch wire spacing this is not a cage for babies or small females, and one reviewer reports an escape through the wide bars.
It carries the lowest average rating here at 4.0 stars, with a higher share of one-star reviews than the other cages. Check the latch and wheel legs on arrival.
How Big Does a Rat Cage Need to Be for Two Rats?
You will see figures from 2 cubic feet per rat to 5 cubic feet per rat across different sources, which is why new owners get stuck. The community enclosure guide from r/RATS suggests roughly 50 by 100 by 50 centimetres, about 8 to 9 cubic feet, for a pair. That is the number we use.
The math is simple: measure the internal length, width and height in inches, multiply the three together, then divide by 1728 to get cubic feet. Manufacturers list external dimensions, so subtract an inch or two per side for the frame and trays.
Then add about 20% for what goes inside. Hides, a large igloo, a hammock, a wheel and eight inches of bedding for burrowing all take usable space away from the rats. If your calculated total lands under 8 cubic feet, the cage is a secondary space rather than a home.
Tall or long is the next question, and the answer is long for floor activity and tall for climbing. Wide rectangular bases beat square ones, since rats run straight lines. If you are planning other purchases for the same room, our guides to ceramic sets for two and two-stage snow blowers cover the same kind of household setup thinking.
What Bar Spacing Do Two Rats Need?
Half inch is the standard, and it is the number to insist on. Wider spacing puts babies and small females at risk, and adult rats are excellent escape artists when motivated. Never size down for a pair, because a bonded pair is the easiest arrangement to keep.
Three-eighth inch is the narrowest in this roundup and works well, giving no gap a rat can exploit. Anything at seven-eighth inch or wider, including the 1.1-inch option here, is an adult-only cage. Measure the gap yourself with a coin rather than trusting the listing.
Bar orientation is worth a note too. Horizontal bars on the walls and floor let rats climb anywhere, which they will do. The Critter Nation Double Unit lists half-inch horizontal spacing, which is the safer configuration for animals that climb as eagerly as rats do.
Floors, Ledges and Bumblefoot
Bumblefoot is an inflammatory condition of the paw pads caused by standing on wire. Several cages here use a metal grate floor, including the Yaheetech, the Homey Pet and the Mcage. Covering the grate with fleece, cardboard or a solid tray liner is treated as essential by experienced keepers, not optional.
Full-length floors beat corner ledges. A shelf that spans most of a level gives a flat surface to land on, while a small corner ledge means a drop from the platform to the floor below. The community guide puts the maximum safe fall at 20 inches, and older rats with less agility need that margin.
Keep the tray deep. Around four inches minimum per the r/RATS guidance, with eight inches of bedding above it for burrowing. Rats that cannot dig become restless, and restless rats chew the cage instead of the enrichment you bought for them.
What to Avoid in a Rat Cage
Wood soaks urine, cannot be washed properly and gets chewed. Reviewers with wood cages describe permanent odour and regret. Plastic-base cages are chewed through within months by determined rats, so all-metal is the safer choice for a pair.
Aquariums and glass tanks trap ammonia from urine, and rats have sensitive respiratory systems. Good airflow across the whole enclosure matters more than looking attractive, which is why barred metal cages dominate this list.
Avoid buying the smallest cage as a starter with no second plan. Owners on rat forums commonly buy a small cage for babies and later repurpose it as a quarantine and hospital cage, but the main habitat should be big enough that you never need to replace it.
Finally, place the cage away from direct sun, drafts, radiators and cleaning products, and keep the room between 68 and 77F. Our home gym cage guide takes the same floor-space-first approach to a different kind of enclosure.
Frequently Asked Questions
What are the best rat cages for two rats?
The best rat cages for two rats are multi-level metal enclosures with solid or covered floors, half-inch bar spacing and at least 8 cubic feet of usable space. Our top pick is the Critter Nation Double Unit, which has two full levels, half-inch horizontal bars and splits into two separate spaces for quarantine or separation.
How big does a rat cage need to be for two rats?
Aim for roughly 50 by 100 by 50 centimetres, about 8 to 9 cubic feet, for a pair of rats. Multiply internal length by width by height in inches and divide by 1728 to get cubic feet, then add around 20% for bedding depth, hides, hammocks and toys.
What bar spacing do rats need?
Half-inch bar spacing is the standard for rats and keeps babies and small females contained. Three-eighth inch is narrower and also works. Anything at seven-eighth inch or wider, including 1-inch and 1.1-inch spacing, suits full-grown adults only and puts young rats at risk of escaping.
Do rats prefer tall or long cages?
Both, for different reasons. Long rectangular floor areas suit running and straight-line racing, which rats do constantly, while height gives climbing routes. Wide rectangular bases use floor space better than square ones, and full-length floors are safer than small corner ledges because they reduce fall height.
What type of cage is best for keeping two rats?
A metal barred cage with a removable plastic base tray, full-width doors, ramps with secure surfaces and covered or solid floors is the best type for two rats. Avoid wood, plastic-sided cages and glass aquariums, and cover any wire grate floor to prevent bumblefoot.
Is 2 rats better than 1?
Rats are social animals and are generally better kept in pairs or small groups than alone. A bonded pair keeps each other company and grooming, which reduces stress. Introduce them properly, and be prepared to spend a few weeks on scent swapping before they share a cage.
The Best Rat Cages for Two Rats
The Critter Nation Double Unit is the best rat cage for two rats overall, because it pairs half-inch horizontal bars with two genuine full levels and more than 6,000 owner reviews behind it. If your rats are adults and you want more volume plus a storage stand, the Prevue 485 is hard to beat.
On a tighter budget, the Homey Pet cage gives you a rat-specific layout with an anti-spill base, while the SUPER DEAL 4-Tier ships with ladders, bowls and a water bottle already included. Add a narrow-bar cage like the Mcage for vet trips and cleaning days, and you cover every situation a pair of rats creates.
Whatever you choose, verify the bar spacing with a coin, cover any wire grate floor, and give them eight cubic feet or more. That is the whole secret to the best rat cages for two rats, and the picks above all clear it once you match the cage to your rats’ age.
