Diet: Make sure your mouse has clean water available all day, every day. Mice are tiny, and they dehydrate quickly. A drip-bottle or two on the side of the cage will work well. A good quality pet mouse food is readily available. Mice eat more than you’d expect for critters their size, so make sure fresh pellets are always available for them. A piece of dog biscuit is a nice treat a couple times a week, and it doubles as a chew toy to wear down their teeth. Tiny pieces of apple or carrot, a few pieces of unsweetened breakfast cereals are all tasty and nutritious items to round out the diet. Most mice dislike cheese, by the way, and it isn’t particularly good for them. If you discover that yours have a taste for cheddar or brie, a tiny piece once or twice a week is okay for a treat.
Housing: Mice are great pets for homes with children, but children should not be allowed to handle the animals without an adult supervising them. It’s also important to wash your hands before and after handling mice. They can catch “colds” from you.
If there are other pets in the home, keep your mice safely away from any animals that might see them as “lunch.” This includes cats, ferrets, dogs, snakes, and rats.
Keep the mice out of direct sunlight and drafts, too. It’s very easy for a mouse to over-heat enough to kill her. In the summer, you may need to put an ice-pack in one side of the cage, to let the mice cool themselves. If you use a gel ice-pack, be sure it’s non-toxic. Mice love to chew.
Commercial bedding is available to purchase for your pet mice. Fill the bottom of the cage with paper made bedding a few inches thick. Provide a few pieces of paper towel or facial tissue, for the mice to make their little nests with, and they will be happy.
