Small pets have an uncanny ability to follow their curiosity to unknown places beyond the walls of their cages and habitats. Using their wit and wile they often find themselves wandering the halls of your house, exposed to all the dangers that come with that territory. To help prevent this dangerous situation, as well as a long and frustrating search and rescue for you and your family, you should make sure you know how to keep your small animal, be it a rat or mouse or hamster, in his cage.
