Guinea pigs are among the most commonly kept small pets but are frequently housed in conditions that fail their social and physical needs. Simple changes make a significant difference.
Guinea pig welfare failures are widespread and largely invisible to the public. Solitary housing is among the most common and most damaging mistakes — guinea pigs are obligate social animals that experience chronic stress when kept alone. Inadequate space, no access to hay as the dietary foundation, vitamin C deficiency from insufficient fresh vegetables, and lack of hiding places are other common failures. Guinea pigs vocalize distress through teeth chattering and are alert to human handling approaches, yet their subtle behavioral signals are often missed. Education at the point of sale and improved welfare standards for pet retailers would substantially improve outcomes.
