Rats are intelligent, social animals that need far more space than most pet shop cages provide. The best rat cage in the UK should be multi-level, have appropriate bar spacing, and offer easy cleaning access. This guide reviews the top cages available in 2026 for 2–6 rats.
⚠️ Welfare note: Bar spacing is the single most critical safety factor. Adults: max 1 inch (2.5cm). Young or small rats: max ½ inch (1.27cm). Wide-bar cages designed for rabbits or birds are dangerous for rats.
Top Rat Cages — UK 2026
1. Savic Royal Suite 95 ⭐ Best Overall
The Savic Royal Suite 95 is the gold standard for UK rat keepers. With its large double-door front opening, multiple full-level platforms, pull-out tray, and solid build quality, it’s the most recommended cage on UK rat forums. The bar spacing (1.25cm) is safe for adult rats, and the full-width shelves eliminate fall risks. It comes on wheels for easy relocation during cleaning.
Dimensions: 95 × 57 × 100cm | Bar spacing: 1.25cm | Levels: 3 full platforms
2. Liberta Explorer — Best for 4–6 Rats
At 93 × 63 × 159cm, the Liberta Explorer is one of the largest cages in the UK market and genuinely suitable for a group of 6 adult rats. Full-height double doors open from the front for easy access, metal shelves are solid (no mesh fall risk), and the wheels make cleaning practical. The base tray is shallower than ideal — adding a dig box for burrowing enrichment is recommended.
Dimensions: 93 × 63 × 159cm | Door access: Full front double doors | Suitable for: Up to 6 rats
3. Little Zoo Venturer — Best Budget Large Cage
The Little Zoo Venturer (93 × 68 × 158cm) offers impressive floor space at a lower price point. Two large double doors, a metal base (more durable than plastic), and wheeled mobility make it a practical choice. Bar spacing is appropriate for adult rats. It’s less refined than the Savic Royal Suite but represents excellent value for the size.
Dimensions: 93 × 68 × 158cm | Base: Metal tray
4. Cozy Pet Large Rodent Cage (RC03) — Best Mid-Range
A well-priced, solid cage from a reliable UK supplier. The Cozy Pet RC03 has appropriate 1.1cm bar spacing, removable trays (making cleaning straightforward), and enough multi-level space for 2–4 rats. The half-opening front is its main limitation — reaching the back corners requires patience. A reliable everyday cage for a small group.
5. Double Critter Nation — Best Premium Option
The Double Critter Nation (USA-origin but available in the UK) is frequently cited as among the best rat cages in the world. The full-opening double doors, large interior, and modular expandability are unmatched. Available through specialty UK rodent suppliers, it comes with a premium price (~£200+) but offers the most usable space and access of any cage in the category.
Buying Guide: What to Look For
Bar Spacing — Critical Safety Check
- Baby/young rats: Maximum ½ inch (1.27cm)
- Adult rats: Maximum 1 inch (2.54cm) — small adult females may still escape through 1 inch bars
- Always: Check the diagonal spacing, not just horizontal/vertical
Size: How Much Space Do Rats Need?
The RSPCA and National Fancy Rat Society recommend a minimum of 70cm × 35cm floor space per pair, though larger is always better. A working guide for group sizes:
| No. of Rats | Minimum Cage Size | Recommended |
|---|---|---|
| 2 rats | 70 × 35 × 50cm | Savic Royal Suite or equivalent |
| 3–4 rats | 80 × 50 × 100cm | Liberta Explorer or Savic XL |
| 5–6 rats | 100 × 50 × 150cm | Double Critter Nation or Liberta Explorer |
Multi-Level Design
Rats are natural climbers and should have multiple levels for enrichment. Look for:
- Solid (not mesh) floor platforms — mesh flooring causes bumblefoot, a painful foot condition
- Horizontal bars wherever possible — rats prefer climbing horizontally
- Ramps and ladders to connect levels safely
Access and Cleaning
Large double-doors that open fully (like the Savic Royal Suite or Double Critter Nation) make daily maintenance and socialisation far easier. Cages with pull-out base trays allow quick spot-cleaning without disassembly.
Avoid Aquariums
Glass tanks have poor ventilation, leading to ammonia build-up from urine. This causes respiratory problems — one of the most common health issues in rats. Wire cages with solid platforms are always preferable.

FAQs
Can rats be kept in rabbit or bird cages?
Sometimes — but always check bar spacing first. Many rabbit cages have 2.5–3cm spacing which adult rats can squeeze through, and that prey animals can fall through. Always measure before buying.
How many rats should I keep together?
Rats are highly social and should never be kept alone. A minimum of two same-sex rats is the RSPCA recommendation. Groups of 3–6 are common and well-suited to large cages like the Liberta Explorer.
How often should I clean a rat cage?
Spot-clean daily (remove soiled bedding, clean water bottles). Full cage cleans should happen once or twice weekly — rats are prone to ammonia sensitivity, so maintaining low odour is essential for respiratory health.
