Guinea pigs are highly social herd animals whose welfare is frequently compromised by solitary housing, inadequate space, and preventable health conditions in captive settings.
Guinea pig welfare is routinely compromised by misunderstandings about their fundamental needs. Solitary housing causes chronic stress in an animal whose natural state involves constant group contact and communication. Inadequate space restricts exercise and causes boredom. Dental disease — which develops slowly and causes prolonged suffering before owners notice — is preventable through hay-dominated diets. Providing compatible same-sex pairs or groups, adequate floor space, and appropriate nutrition are the foundations of guinea pig welfare that every owner should understand before acquiring these animals.
