Best Rat Cage Materials for a Safe and Comfortable Habitat
Choosing the right rat cage materials is important for durability, safety, and cleanliness. Some materials are better suited for pet rat enclosures than others.
Recommended Rat Cage Materials
- Powder-Coated Metal – Chew-proof, sturdy, and well-ventilated.

A cage for rats should always have proper ventilation and plenty of space for movement.
Fancy Rat vs. Dumbo Rat: Does Size Affect Cage Needs?
How Big Does a Fancy Rat Get?
- Fancy rats are slightly larger than standard rats, averaging 9 to 11 inches in body length, plus a 7 to 9-inch tail.
