Guinea pigs (cavies) can be a great addition to any family! Being larger than other pocket pets, guinea pigs are usually a good match for small children. They are daytime critters and are slower moving than hamsters or gerbils, making them easier to handle. They also have a generally happy disposition and rarely bite. This, along with their amusing squeaks, grunts and adorable looks, makes guinea pigs an irresistible small pet.
