Best Rat Cages UK 2026: Space, Safety and Value
Choosing the right cage for your rats comes down to three things: bar spacing narrow enough they can't escape, floor space big enough for a pair to live comfortably, and a design you can actually clean without dreading it. We compared six rat cages sold in the UK on build quality, dimensions, ease of cleaning and value, so each pick below fits a specific situation.
Key Takeaways
- MidWest Critter Nation Single Unit - Best overall for serious rat owners. Massive floor space, full-width doors for easy cleaning, and a rolling stand. The gold standard in the rat community.
- Little Friends Chatsworth Double - Best mid-range option. Two full-height sections with narrow 1cm bar spacing, solid construction and good value for a multi-rat setup.
- Cozy Pet RC05 - Best value. 11mm bar spacing at a lower price than the RC03, with metal shelves and three platform levels for climbing.
- Little Friends Langham - Best budget starter cage. Under ยฃ70, comes with accessories, and narrow 1cm bar spacing. Suits one or two young rats before you upgrade.
- Yaheetech 175cm - Best tall cage. Three tiers at 175cm height with rolling castors. Great for rats who love climbing, though the base footprint is narrower than Critter Nation.

Our Quick Picks
Rats are among the most social and intelligent small pets you can keep in the UK. They need room to explore, climb and nest, and a cramped cage leads to boredom, obesity and respiratory problems from ammonia buildup. The RSPCA recommends a minimum of 0.5 square metres of floor space for a pair, though bigger is always better.
We compared six of the most popular rat and small animal cages available on Amazon UK using manufacturer specifications, Amazon purchaser ratings and independent owner feedback. The comparison focused on bar spacing (the number one safety factor for rats), floor space, build quality, ease of cleaning, and how well each cage accommodates the accessories rats actually need: hammocks, shelves, deep bedding and chew toys.

In-Depth Reviews
1. MidWest Critter Nation Single Unit
Price: ~ยฃ142 | Dimensions: 76L x 46W x 107H cm | Bar Spacing: 2.5cm | Weight: 18kg
The MidWest Critter Nation is the cage that serious rat owners recommend over and over. Its 76x46cm floor space gives a pair of rats genuine room to move, and the full-width front doors mean you can reach every corner for cleaning without disassembling anything. The rolling stand makes it easy to move for floor cleaning, and the leak-proof pan catches bedding and waste.
Amazon purchasers consistently highlight how easy it is to clean compared to other large cages. The ramps have a plastic coating that prevents bumblefoot, and the shelves are covered in a chew-resistant material. One Amazon reviewer noted: "We upgraded from a smaller cage and the difference in our rats' behaviour was instant. They use every inch of this cage."
The main consideration is the 2.5cm bar spacing. For adult male rats this is fine, but young rats or small females could potentially squeeze through. If you have baby rats, you may need to add mesh until they grow. The cage also ships flat-packed and takes around 30 minutes to assemble.
- Massive 76x46cm floor space
- Full-width doors for easy cleaning
- Rolling stand included
- Chew-resistant shelf covers
- Most-reviewed rat cage on Amazon UK
- 2.5cm bar spacing may not suit small/young rats
- Takes up significant floor space
- Flat-pack assembly required
2. Cozy Pet Large Rodent Cage RC03
Price: ~ยฃ165 | Dimensions: 92L x 65W x 159H cm | Bar Spacing: 12mm | Weight: 34kg
The Cozy Pet RC03 is built specifically for owners who need narrow bar spacing. At 12mm, it's designed to contain even the smallest rats and young pups without risk of escape. Cozy Pet has been selling rodent cages on Amazon UK for nearly a decade, and the RC03 is their largest model with metal shelves and ramps that resist chewing.
The 92x65cm footprint is generous, and the 159cm height across five tiers gives rats plenty of vertical space for hammocks and climbing. Amazon purchasers praise the build quality and the metal trays, which are far more durable than plastic alternatives. The cage ships in two cartons and weighs 34kg, so it is a genuinely heavy piece of kit.
The main drawback is the price. At ยฃ165, it costs more than the Critter Nation while offering a different trade-off: narrower bars but a less user-friendly cleaning experience. The doors are smaller, and reaching the back shelves requires more effort. It is the right choice if bar spacing is your top priority, but the Critter Nation wins on day-to-day usability.
- 12mm bar spacing safe for all ages
- Five tiers with metal shelves
- 92x65cm generous footprint
- Heavy-duty construction
- Narrow 12mm bars prevent escape
- Expensive at ยฃ165
- Smaller doors make cleaning harder
- Very heavy (34kg) once assembled
- Ships in two cartons
3. Cozy Pet Rodent Cage RC05
Price: ~ยฃ105 | Dimensions: 80L x 52W x 127H cm | Bar Spacing: 11mm | Weight: 22kg
The Cozy Pet RC05 splits the difference between the RC03's premium pricing and the Langham's starter positioning. At 11mm bar spacing, it actually has the narrowest gap in this comparison, making it safe for even the smallest rats. The 80x52cm floor space is adequate for a pair, and the three platform levels give rats climbing space without excessive height.
Cozy Pet's cage range uses heavy-duty box-section steel with a pet-safe silver-grey powder coat. The ABS plastic trays pull out for cleaning, and the metal grid above the tray protects plastic from chewing. Amazon purchaser reviews highlight that the cage is straightforward to assemble with the included Allen key, and the safety latches on the doors are secure.
At around ยฃ105, the RC05 is the most affordable narrow-bar option. It is smaller than the RC03, so it works best for one or two rats rather than a larger group. If you want narrow bar spacing without the ยฃ165 price tag, this is the cage to pick.
- Narrowest bar spacing at 11mm
- Good price for the build quality
- Metal shelves resist chewing
- Easy to assemble with Allen key
- Pull-out ABS trays for cleaning
- Smaller than the RC03
- Plastic ramps (may be chewed)
- Fewer reviews than the Critter Nation
4. Little Friends Chatsworth Double
Price: ~ยฃ98 | Dimensions: 80L x 48W x 80H cm | Bar Spacing: 1cm | Weight: 15kg
The Little Friends Chatsworth Double is a two-section cage with super-narrow 1cm bar spacing, designed specifically for rats, chinchillas and ferrets. The double-height design gives you two full levels connected by ramps, and each section has its own front-opening door for easy access.
At 80x48cm, the floor footprint is solid for a pair of rats, and the 80cm total height across two sections provides decent vertical space. The cage includes two shelves, two ladders, and the narrow bar spacing means even baby rats cannot escape. Amazon purchasers rate it highly for build quality and the ease of putting it together.
Under ยฃ100, this is a strong value option for rat owners who want proper bar spacing without paying for a massive cage. It is smaller than the Critter Nation, so it suits a pair rather than a larger group. If you want a well-built mid-range cage with zero escape risk, the Chatsworth hits the mark.
- 1cm bar spacing safe for all ages
- Two full-height sections
- Under ยฃ100 with good build quality
- Front-opening doors on each section
- Includes shelves and ladders
- Smaller footprint than Critter Nation
- Not ideal for 3+ rats
- Wooden shelves may need protecting from chewing
5. Yaheetech 175cm Small Animal Cage
Price: ~ยฃ118 | Dimensions: 78L x 51W x 175H cm | Bar Spacing: 2.1cm | Weight: 15kg
The Yaheetech 175cm is the tallest cage in this comparison, with three full tiers across 175cm of height. It sits on a rolling stand with a storage shelf underneath, and each tier has a full-width door for cleaning and access. Rats who love climbing will use every level, and the height means you can hang multiple hammocks across different tiers.
The 78x51cm base footprint is slightly smaller than the Critter Nation, but the vertical space compensates for it. The 2.1cm bar spacing is fine for adult rats but may not be suitable for very young or small females. Amazon purchasers report good build quality for the price, with the main complaint being that the plastic base tray could be deeper for holding bedding.
At ยฃ118, this is a strong option if vertical space matters more than a massive floor footprint. It suits active rats who enjoy climbing and exploring different levels. Pair it with plenty of hammocks and ramps to maximise the usable space on each tier.
- 175cm height with three tiers
- Rolling stand with storage shelf
- Full-width doors on each level
- Good value at ยฃ118
- 680+ Amazon ratings
- 2.1cm bar spacing not ideal for small rats
- Narrower base than Critter Nation
- Plastic base tray is shallow
6. Little Friends Langham Tall Rat Cage
Price: ~ยฃ67 | Dimensions: 78L x 48W x 58H cm | Bar Spacing: 1cm | Weight: 7.4kg
The Little Friends Langham is the most affordable cage in this comparison and the one most first-time rat owners start with. At under ยฃ70, it comes with two shelves, two ladders, two hide houses, two wheels and two food bowls. The 1cm bar spacing is safe for all rat sizes, and the cage is easily collapsible for storage.
The 78x48cm floor space is enough for one or two young rats, though adult pairs will outgrow it over time. Amazon purchasers rate it highly for value, with an average of 4.5 stars across more than 1,200 reviews. One Amazon reviewer noted: "Perfect starter cage for our first pair of rats. They loved the shelves and it was easy to put together."
Think of this as a stepping-stone cage rather than a forever home. It is brilliant for the first few months while your rats are young, but you will likely want to upgrade to a Critter Nation or Chatsworth as they grow. At the price, it is hard to beat for getting started.
- Under ยฃ70 with accessories included
- 1cm bar spacing safe for all sizes
- 1,282+ Amazon ratings at 4.5 stars
- Collapsible for easy storage
- Lightweight and easy to move
- Small for adult pairs
- Supplied wheels are too small for rats
- Wooden shelves may need protecting
- Not a long-term solution for growing rats
Rat Cage Buying Guide
Bar Spacing: The Non-Negotiable
Bar spacing is the single most important safety factor when choosing a rat cage. Rats, especially young ones and females, can squeeze through gaps that seem impossibly small. The safe maximum is 13mm (half an inch). Anything wider than that carries escape risk for babies and smaller rats. The Cozy Pet RC05 at 11mm and the Little Friends cages at 1cm are the safest options in this comparison. The Critter Nation at 2.5cm works for adult males but needs mesh covering for young rats.
Floor Space vs Height
Rats are ground-dwelling animals that also love to climb. The ideal cage gives you both: a large floor area for running and burrowing, and vertical space for hammocks, shelves and ropes. The minimum for a pair is around 0.5 square metres of floor space, but bigger is always better. A cage with 0.75 square metres or more gives rats room to establish separate sleeping spots, which reduces squabbling.
Material and Build Quality
Wire cages with plastic base trays are the standard. Metal shelves and ramps are more durable than plastic ones, which rats will chew over time. The Cozy Pet range uses metal ramps and shelves, while the Little Friends cages have wooden shelves that may need protecting with chew guards. Look for powder-coated wire rather than bare metal, and pull-out trays that make cleaning straightforward.
Cleaning and Maintenance
Rats produce more waste than hamsters, so cage cleaning frequency matters. Full-width doors (like the Critter Nation) make daily spot-cleaning much easier than small access hatches. Pull-out trays are essential. Plan for a full clean with pet-safe disinfectant once or twice a week, with daily removal of soiled bedding and uneaten food.
Accessories Rats Actually Need
A bare cage is a bored rat. Essential accessories include: hammocks (rats sleep in them more than on shelves), a solid-surface exercise wheel at least 28cm diameter, deep paper-based bedding for nesting (at least 5-8cm), chew toys for dental health, tunnels and hide houses, and a water bottle. Avoid wheels with bars or rungs, which can trap tails and feet.
Frequently Asked Questions
What bar spacing is safe for rats?
A bar spacing of 13mm (half an inch) or less is considered safe for all rat ages and sizes. Young rats and small females can squeeze through wider gaps, so narrower is always better. The Critter Nation has wider 2.5cm spacing, which works for adult males but may not suit babies or small females.
How big should a rat cage be?
The minimum recommended size for a pair of rats is around 0.5 square metres of floor space, with 0.75 square metres or more being ideal. Vertical space also matters since rats love to climb, so a tall multi-level cage with shelves and hammocks gives them more usable area. For three or more rats, go as large as your space allows.
Can two rats live in the same cage?
Yes, rats are highly social and should ideally live in same-sex pairs or groups. A single rat will often become lonely and stressed. Same-sex siblings raised together get along best. Introduce new rats slowly using the neutral-territory method to avoid fighting.
What accessories do rats need in their cage?
Essentials include hammocks or shelves for climbing and sleeping, a water bottle, a food dish, chew toys for dental health, and deep bedding (at least 5-8cm) for nesting. Rats also benefit from tunnels, hide houses and foraging toys to keep them mentally stimulated. Avoid running wheels with bars - solid-surface wheels are safer.
How often should I clean a rat cage?
Spot-clean daily by removing soiled bedding and food waste. A full cage clean with pet-safe disinfectant should happen once or twice a week, depending on the number of rats and cage size. Rats produce more waste than hamsters, so staying on top of cleaning helps prevent respiratory issues.
What is the best rat cage for beginners?
The Little Friends Langham is a solid starter choice. It has narrow 1cm bar spacing, comes with basic accessories, and costs under ยฃ70. It suits one or two young rats, though you may want to upgrade as they grow. For a buy-once option, the MidWest Critter Nation is the gold standard.
Final Verdict
The MidWest Critter Nation is the best rat cage for most UK owners. Its floor space, full-width doors and rolling stand make daily life with rats genuinely easy. If bar spacing is your top priority, especially for young or small rats, the Cozy Pet RC05 gives you 11mm narrow bars at a fair price. For first-time owners on a budget, the Little Friends Langham gets you started for under ยฃ70 with zero escape risk. Whichever cage you choose, remember that rats need more than a cage, they need enrichment, companionship and space to be rats.
