Commercially available cages are everywhere, whether bought on pet stores or online markets. You can also make your own rat cage. In choosing the right cage for your rat, you must take into consideration how many rats are you going to have.


It is important that each rat gets enough space to explore and climb within a cage. You must have at least 1.5 – 2.5 cubic feet of cage space per rat. There are some cage space calculators online if you don’t like having to calculate it yourself.


Pre-made rat cages come in various types of materials. These are:

Plastic: Although less expensive and easy to clean as well as aesthetically-pleasing, rats have strong teeth, which they can use to chew holes on plastic cages.

Powder coated metal or wire cages: This type of cage is highly recommended since it is quite sturdy and easy to clean.

Galvanized Wire Cage: Rat urine can easily stain the wire and may corrode it at some point. This type of cage is quite high-maintenance.

Easy Access for Cleaning

When you look for a rat cage, choose one which you can clean easily. Consider these factors in rat cage when you’re planning to buy one:

  • Has removable floor tray
  • Has a lot of wide doors
  • Has a detachable top and base
  • Has solid flooring
  • Is easy-to-reach

Spacing of bars

A 1-inch bar spacing is adequate for an adult pet rat, but if you own a younger rat or plan to have baby rats, opt for a cage with 1/2 inch or smaller bar spacing.


It is an important factor to consider when you plan to purchase rat cages. Rats need proper ventilation in order to be healthy and stress-free. Avoid putting your rats in glass aquariums or cages with poor ventilation.
