Small mammals including hamsters, gerbils, and guinea pigs are among the most commonly kept yet most commonly neglected companion animals.
Small mammal welfare receives less attention than dogs and cats despite equally important behavioral needs. Hamsters, gerbils, and guinea pigs are frequently given to children with inadequate information about their requirements. Tiny commercial cages prevent natural locomotion, burrowing, and exploration. Solitary housing of social species causes chronic stress. Short lifespans make these animals seem low-commitment, reducing the care investment owners make. Species-appropriate housing, diet, and social grouping can dramatically improve the welfare of millions of small pets.
