Guinea pigs are among the most commonly kept small pets, but their welfare is frequently compromised by inadequate housing, solitary keeping, and insufficient understanding of their social and dietary needs.
Guinea pig welfare is frequently compromised by the perception that they are low-maintenance starter pets for children. In reality, guinea pigs have complex social, dietary, and space needs that require genuine commitment to meet. Solitary keeping — still common — causes chronic stress in an animal whose entire evolutionary history is social. Inadequate housing in small commercial hutches restricts movement, foraging, and social interaction simultaneously. The mismatch between the image of guinea pigs as easy pets and the reality of their welfare needs makes them one of the most commonly welfare-compromised companion animals in households that mean well but are inadequately informed.
