The Most Common Question About Mice
What style and size home is the best for my pet mouse?
Pet mice need a home suited to their instincts. Just because a mouse is relatively small, it does not mean his home should be. In fact, as with any pet, the bigger the home the better your mouse will be. Choose a cage or habitat that affords your mouse enough room to move about, climb, and nest. If you have multiple pet mice, make sure their home is big enough to accommodate each comfortably. As a general rule, if you have four or five pet mice, the cage should be at least 12" wide x 14" long. Multiple level homes are a plus, because your mice can get away from each other when they want.
The best style of home is a wire cage with, at most, 3/8" spaced wires. Unlike traditional screen-covered aquariums, wire cage homes allow your mouse to climb and play. In addition, wire cages offer adequate ventilation. It is also important that your mouse's home includes ramps, climbing platforms, ladders, or exercise wheels. Mice are very active animals who require physical activity. Regardless of how large your pet's home is, however, make sure you regularly clean it on a daily and weekly basis. Contrary to popular belief, mice don't like messes. Dirty cages are harmful to both you and your pet's health.
