Pet rats are intelligent, social, and endlessly entertaining companions, but they have very specific housing requirements. A proper rat cage isn't just a place for them to sleep — it's their entire world. Rats need vertical space for climbing, solid flooring to prevent foot injuries, good ventilation, and enough room to accommodate multiple rats (since they should never be kept alone).
The best rat cages feature multiple levels, wide doors for easy cleaning, deep base pans to contain bedding, and bar spacing narrow enough to prevent escapes. They also need to accommodate accessories like hammocks, ropes, wheels, and hiding spots that make a rat's life truly enriching.
In this guide, we've reviewed the 5 best rat cages and essential accessories available in 2026, from budget-friendly starter cages to premium multi-level condos. We've also included essential accessories that every rat owner should consider.
What to Look for in a Rat Cage
- Size: Minimum 2.5 cubic feet per rat. A cage of at least 24" × 18" × 24" is a good starting point for a pair.
- Bar spacing: No more than 1/2 inch for adults, 1/4 inch for babies. Rats squeeze through surprisingly small gaps.
- Ventilation: Wire or mesh sides are essential. Glass aquariums trap ammonia fumes that cause respiratory problems.
- Solid floors: At least some solid platforms are necessary. Wire floors cause bumblefoot (painful foot infections).
- Accessibility: Large doors or removable tops make weekly deep cleaning much easier.
- Vertical space: Rats are natural climbers. Multiple levels connected by ramps, ladders, or ropes keep them active.

Frequently Asked Questions
How many rats should I keep together?
A minimum of two rats is essential. Groups of 3-4 are even better. Same-sex pairs or groups unless breeding.
How often should I clean the cage?
Spot-clean daily. Full bedding change every 5-7 days. Deep clean every 2-4 weeks.
Can I use a glass aquarium?
No. Poor ventilation leads to ammonia buildup and respiratory infections — the #1 health problem in rats.
What bedding is safest?
Paper-based bedding (Carefresh, Kaytee Clean & Cozy), aspen shavings, or kiln-dried pine pellets. Avoid cedar and aromatic pine.
Do rats need a wheel?
Yes, but a large solid-surface wheel (12+ inches). Wire or small wheels cause injuries.
