Bringing home a pair of fancy rats is an exciting moment, but finding the right cage can be overwhelming. Our editorial team researched the best options that meet the unique needs of these intelligent, social rodents.
Fancy rats need spacious, multi-level cages with narrow bar spacing to prevent escapes and good ventilation. We looked for secure latches, easy-clean pans, and accessories that support climbing and enrichment. Below are our top picks based on real market research.
The Options
Types Explained
Multi-Level Wire Cages
These are the most common and recommended for fancy rats. They provide vertical space for climbing, good ventilation, and often include shelves and ramps. Bar spacing must be narrow enough to prevent escape.
Converted Bird Cages
Large bird cages can be repurposed for rats if bar spacing is appropriate (0.5 inches or less). They often offer more height and floor space than standard rat cages, but may need modifications like removing perches and adding solid flooring.
Modular Cages
Modular systems like Critter Nation allow you to stack or connect multiple units to expand living space. They are highly customizable and provide excellent access for cleaning and interaction.

Fancy rats can squeeze through gaps larger than 0.5 inches. Look for bar spacing of 0.5 inches or less to prevent escapes or injuries. For baby rats, 0.4 inches is even safer.
02
Cage Size and Height
Rats need vertical space for climbing. A minimum of 2.5 cubic feet per rat is recommended, but bigger is better. Choose a cage with multiple levels and at least 30 inches in height.
03
Door Access
Large, full-sized doors make cleaning and interacting with your rats easier. Cages with multiple doors allow better access to all levels. Avoid cages with tiny doors that make reaching inside difficult.
04
Base Depth
A deep plastic base (at least 3 inches) helps contain bedding and waste, reducing mess outside the cage. Wire floors should be avoided as they can hurt rat feet; solid floors are preferred.
05
Ventilation and Material
Wire cages with good airflow prevent respiratory issues common in rats. Avoid all-glass aquariums due to poor ventilation. Powder-coated metal is durable and easy to clean.
Living With It
Care, Cost and Maintenance
Cleaning Schedule
Spot clean soiled bedding daily and do a full cage clean weekly. Use a rat-safe disinfectant and rinse thoroughly. Replace all bedding, wash accessories, and wipe down bars to prevent ammonia buildup.
Bedding Choices
Use paper-based or aspen shavings for bedding. Avoid pine or cedar as they contain oils harmful to rats. Provide a deep layer (2-3 inches) for burrowing. Fleece liners can be used on shelves but need frequent washing.
Enrichment Essentials
Add hammocks, tunnels, ropes, and chew toys to keep rats stimulated. Avoid plastic accessories that can be chewed and ingested. Provide a solid exercise wheel (12 inches diameter minimum) for physical activity.
Pro tip
Our team suggests placing the cage in a quiet, draft-free area away from direct sunlight and extreme temperatures. Rats are sensitive to respiratory irritants, so avoid placing the cage near kitchens or bathrooms. Always provide a companion for your rat, as they are highly social and thrive in pairs or groups.
Frequently asked questions
Can I use an aquarium for my fancy rat?
No, all-glass aquariums are not recommended due to poor ventilation, which can lead to respiratory problems. Wire cages with narrow bar spacing are much safer and healthier for rats.
How many rats can I house in a single Critter Nation?
A single Critter Nation unit is suitable for 2-3 adult rats. If you have more rats, consider adding a second unit to stack, providing more vertical space and enrichment opportunities.
What bar spacing is safe for baby rats?
For baby rats, bar spacing of 0.4 inches or less is recommended to prevent them from squeezing through. Adult rats can safely have up to 0.5 inch spacing, but always supervise young rats.
