This chapter explores the world of small and furry pets: rodents, rabbits, and ferrets. Pet rodents are small and relatively easy to care for. They range from the pudgy and cute hamster to the surprisingly intelligent rat. Rabbits are not rodents, but a separate order known as lagomorphs. They have soft eyes and coats and wiggly noses that endear them to many people. Unlike the others mentioned here, the pet ferret is a carnivore—a meat-eater, like a dog or a cat. Originally, the ferret was used to hunt small prey, but today many ferrets are kept as entertaining and energetic companions.
