A House For Your Mouse (or rat)
(Cages)
Part 3
Note: The number of animals appropriate to each cage will vary greatly by the age/sex/size/personality of the specific animals kept, and often a fewer number than indicated would be ideal.
The rule of thumb with cages is “the bigger, the better.” Please use good judgment. The opinions expressed are
of the author, and may differ from those of other fanciers.

This issue we will cover wire cages and miscellaneous cages.
By far, these are the most common housing on the market. Unfortunately, many cages which can be bought are not suitable for rats.
Mice should not be kept in wire cages — period! They are very small and have been known to squeeze through ridiculously narrow spaces between bars. They also have a tendency to stick their heads through bars or ½ x 1 inch wire mesh and get their heads stuck. This usually causes them to panic and ultimately hang themselves.
There are many different brands of cages, some good, some not so good. I am going to specifically mention the ones I use; however, I have not used and cannot talk about them all.
Basic Guidelines for Buying Wire Cages
There are a number of things to look at and think about before buying
a wire cage. First, consider where you are going to put the cage and how much
space you have. The rule of thumb with cages is “the bigger, the better.” If a
cage has wire shelves or a wire floor, be sure it is made of
½" by ½" mesh. If the mesh is any
bigger, the rats will get their feet caught and break their legs. You can solve this
problem with wire shelves by covering them with plastic needle point canvas.
Some people like cages with wire bottoms; however, this does put the rats at risk
for bumblefoot. Many people simply remove the mesh floor using wire cutters or
needle-nose pliers.It is important to remember that you must be able to remove your rat from their cage, even when they don’t want to come out. Be sure that you can easily reach all corners and floors of the cage. It s important that the door be big enough for not just your hand, but also a full grown rat, plus grabbing little feet.
Remember, our rats are basically ground dwellers. Though they enjoy climbing, they also need adequate floor space. Some cages on the market are very tall with numerous levels, but are extremely narrow. I do not recommend these. A cage should have a base which is at least half as long as the cage is tall.

Pros: Can be very large, provide great opportunities for behavior enrichment, accessories can easily be added, relatively light weight (until you get into large awkward sizes), great ventilation, animals are very visible.
Cons: Can be very large, can be hard to clean, requires scrubbing/hosing/rinsing, rats will scatter shavings, can be drafty, maintenance is more time consuming, metal can develop an unpleasant odor over time, powder coating makes cleaning simpler.
Fern Cage by Sierra
These are one of only two brands of cages which I can recommend
without hesitation. They were designed with rats in mind, and have been used for
some time by southern California fanciers with great success. They were the first
cages truly designed with the health and safety of the animals in mind. No
question, these are a great buy. Most Fern cages are powder coated, have easily
removed pans, solid shelves, and extra large doors. They are easy to clean, give
good access to the critters inside, and come in a variety of sizes. The shelves
are all made of solid powder-coated metal, which is great because the rats cannot trap their
legs and feet in them. On the down side, the solid shelves do collect urine which must be cleaned off daily.
#940 2-shelf Fern Cage with Cat Litter Pan Bottom
- Cost: $25–$40
- Size: 14" x 10" x 18" T
- No. of Animals:
Rats: Good for transporting or temporary housing. Two small rats max. for permanent housing. - Comments: These cages have nice deep pans to limit the amount of bedding scattered. Easily cleaned. This is the minimum size cage you should consider keeping rats in.

#950 3-Shelf Fern Cage with Cat Litter Pan Bottom
- Cost: $35–$70
- Size: 17½" x 10" x 24" T
- No. of Animals:
Rats: 3 males, 4 females max. [preferably only 2 rats] - Comments: Bigger than the 940, with 3 shelves. This is the most popular cage available, and the best buy for the money.

#955 1 Large Shelf Fern Cage with Cat Litter Pan Bottom
- Cost: $30–$70
- Size: 17½" x 10" x 18" T
- No. of Animals:
Rats: 2 males, 3 females max. [preferably only 1–2 rats] - Comments: Just like the 3-shelf, only shorter. This has one wide shelf which is great for males.
#960 2-Shelf Large Fern Cage with Metal Pan
- Cost: $90 up
- Size: 21" x 15½" x 24" T
- No. of Animals:
Rats: Up to 6 females - Comments: As tall as the 950 above, but wider and with more floor space. I like big cages . . . this is my smallest.

#970 3-Shelf X-Large Fern Cage with Metal Pan
- Cost: $100 up
- Size: 24" x 18" x 29" T
- Comments: Has everything the large cage has, only bigger.
Fern Ferret Cage
- Cost: $80 up
- Size: 30" x 15" x 36" T
- No. of Animals:
Rats: Up to 10 females, depending on how often you feel like cleaning. - Comments: Not powder coated, comes with wire shelves but solid ones can be bought from Sierra. Hard to move and clean, but well worth the effort if you have room. I’m a big believer in “the bigger the better” as far as cages are concerned. This is one of my favorites!

Fabricated in Italy for Super Pet. This is the other brand of cage I can highly recommend. They first came to my attention when one of our European rat friends mentioned them. They are made of an odd size wire slightly smaller than 1" x 1" with wire shelves and removable floor made out of wire mesh smaller than ½" x ½". The entire cage comes apart and folds down to fit in just the pan. This makes them very easy to transport. The floor comes out so that the cage can be used with a solid or a wire bottom. Powder coated in a very pleasant off white/tan color.
Small Terenziani Cage
- Cost: $60 and up
- Size: 27" x 16½" x 14" T
- No. of Animals:
Rats: Up to 6 small females - Comments: Entire top opens as a lid for easy access (though this makes stacking impossible). Shelf and floor mesh is small enough not to cause any apparent foot problems. Also comes in much larger ferret/chinchilla sizes. Expensive, but worth it! I haven’t seen these as often in stores recently, so their availability is not known at this time. If you find a used inexpensive one, buy it!
These are fairly new cages on the market and are fast becoming popular, thanks to their easy availability at large chain pet supply stores. My experience comes from one that came along with a group of rescue rats, and if the short term results are representative, these are excellent cages. They come in a number of sizes, colors, and styles.

Ritz Chinchilla/Rat Cage # RC-6
- Cost: $54.99
- Size: 22" X 16" X 19" T
- No. of Animals:
Rats: 2 males, 3 females max. [preferably only 2 rats] - Comments: I’m not sure why this is labeled for Chinchillas, it would be totally inappropriate. On the other hand, it appears to be a very nice cage for rats. This cage is made of bars rather than mesh wire. It would not be an acceptable cage for very young/small rats due to the possibility of them getting their heads between the bars. Older rats, however, find it very acceptable. The shelves consist of bars placed ½" apart and I did not find any problems with rats catching their legs and feet. These eliminate the problem of urine collecting and are nice and wide which the rats seem to like. This cage has a cat litter pan bottom, but the cage part sits up on the edges of the pan instead of inside. The result is more cage space with the same size footprint seen in some of the Fern cages. I actually prefer this cage’s layout because it gives more floor space and shelf space, and less height, while leaving enough room for a wheel. This cage has two shelves, with connecting ladders. It also has an acceptable wheel that surprisingly is large enough for adult female rats. It doesn’t compare with the solid wheels sold by fern, but it is far more acceptable than most others. The door is wide and tall, making access very easy. The only problem I have with this one is the “new spill proof food/water dishes.” If this is a “new” feature, it is a mistake since the bowls cannot be removed without making it possible for the rats to get out.
Converted Rabbit Cages
With minor conversions, rabbit cages can make great rat cages. They
are often spacious, well built, and easy to find. The major problem is that they
are usually equipped with a ½ x 1 inch wire floor, a real no no for rats. Cages
with trays that slide in and out usually cannot be converted; however, those
cages which sit in metal pans can have their bottom cut out. With a few
accessories, these make lovely rat cages.

Converted Bird Cages
These also can make good rat cages. Those made for small birds
(finches, parakeets, cockatiels) are too flimsy, small, and would never hold up to
a rat. Parrot cages on the other hand are excellent. They are spacious, heavy
duty, and well built. All they need are some accessories (ledges, shelves, etc.),
to be the perfect rat house.
Home Made Cages
If you are handy with tools and have the inclination to build your own
cages, it can be easily done. This is a wonderful way to get exactly the features
you want, and do-it-yourself cages are great if you have specific needs.If you choose to go this route, a few things should be kept in mind. Rats are great chewers. They can and will chew on anything they can get their teeth on. Wood and plastic materials are not good choices for this reason. Porous materials (wood, soft plastic, carpet, etc.) are not good materials to use in any portion of the cage because they will become soiled and can not be sterilized. Ease of cleaning is a major factor and this should be a major consideration while planning. You will also want to be able to move the cage in some way, and make sure it fits through doorways, up stairs, etc.

One of the biggest problems with home made cages is their cost. In most cases they end up being significantly more expensive by the time construction is completed.
In Conclusion
As you can see, the choices for housing rats and mice are many and varied.
What is the correct and ideal way to house your rats and mice? Only you
can decide. The solution that fulfills your needs and desires and that your own
animals do well in, is the right one for you.
Do you have a house for your rat or mouse that I haven’t talked about? If it
