Hamsters, gerbils, degus, and other small mammals are commonly kept as pets but frequently housed in ways that compromise their welfare.
Small mammals are among the most commonly mistreated pets, not through deliberate cruelty but through widespread misconceptions about their needs. Hamsters sold in small commercial cages experience chronic stress in undersized environments. Gerbils kept alone develop behavioral abnormalities from loneliness. The gap between commercial pet-keeping norms and what these animals actually need for welfare is wide. Education at the point of sale is particularly important because many owners genuinely do not know they are causing suffering.
