Mice are a wonderful pet for young children just learning to take care of animals, or anyone who would love an active, adorable but low-maintenance pet.

When you’re picking out a mouse, find one that’s active and healthy with bright eyes. Have your veterinarian give your new mouse a checkup first thing. If you’re bringing a new mouse into a group of mice you’ve had for some time, keep him in a sort of quarantine until you’re sure he’s free of any bacterial diseases or viruses.

You can often find mice at pet stores or humane societies that are already accustomed to human handling. If yours isn’t, gentle introduction to being picked up and petted will make your mouse comfortable soon enough. Always approach your mouse slowly and make them aware of your presence before you attempt to pick him up. Tame mice are very easy to handle, and enjoy being petted.

A house for a mouse should be either an open-top aquarium, or a small cage designed for mice, with holes that are too small for them to wriggle out of. Lots of soft bedding—aspen shavings or ink free paper are both good—and a few little areas he can hide in are essential for your mouse’s comfort. Clean and renew bedding material at least every 4 days. Make a separate area inside the mouse house for food—commercial mouse pellets are generally the best choice—and a bottle full of fresh water. All small rodents love toys, and mice are no exception. Don’t throw out those toilet paper rolls or tissue boxes—mice love to chew them to pieces!
