For first-time pet owners, veterinarians often recommend pets smaller than dogs or cats. These can include a variety of rodents such as hamsters, gerbils, rats and mice, although guinea pigs usually top the list for their general durability, especially with children. Smaller pets can be the furry friend that a family may long for without posing the long-term commitment and higher care costs of a dog or cat.

For those that prefer a small furball that isn’t a rodent, a rabbit may be appropriate. “House bunnies are curious and very smart, which can be both terrific fun and problematic,” says Cobin, noting that “house-bun” curiosity, coupled with an intense need to chew, can wreak havoc on cords and other items within reach. “They always have to chew to keep their teeth filed down, but that’s why you give them appropriate things to chew.” Ferrets, members of the weasel family, are also intelligent, and like rabbits, can be trained to use a litter box.
