Habitats for Pet Rats and Mice

Rats and mice do have the same basic needs when it comes to their environment- the main need being space. Use the cage calculators below to determine how many pets the habitat is suitable for. Don't feel limited, however, as bigger is always better! If a larger habitat feels empty, you can always fill it up with toys and other fun things. In addition to space: consider safety, durability, and ease of cleaning.

Wire cages are standard fare among the rat community. Things to keep in mind:

*Always pick galvanized (coated) wire, because unless your rats happen to be completely angelic (which is doubtful ;)) they will chew on the bars and possibly get sick. Galvanized also lasts longer.

*Choose a cage with levels. Rats love to climb.

*If you have babies or small female rats, you'll want to make sure the bar spacing is 1/2 inch or less. Any larger, and they'll be able to slip out!

*Wheels that come with pet store cages can be unsafe. Check for gaps and spaces where a rattie could get a tail or limb stuck; if you see some hazards, pull the sucker out! It's better not to take the risk.

*Test out the doors to make sure they're okay. Rats can be sneaky...

*If you have a cage with a pull-out pan, take out the bottom wire floor. Too much walking on wire can irritate their little feet. On that note, covering all the wire levels (you can use fleece, tile, cardboard, et cetera) with a solid surface is optimal.

Terrariums on their own are /not/ suitable for rats. If you must use one, get a wire cage topper. This will add levels and also provide much-needed ventilation. Clean out the terrarium very often, as ammonia will build up from the urine. This could affect your pet's health, as well as smell unpleasant.

Glass or plastic tanks are always a good way to go for mice.
