Guinea pigs are popular pets whose welfare needs are frequently misunderstood. Understanding their social, spatial, and dietary requirements prevents common suffering.
Guinea pig welfare failures are pervasive and often invisible to well-intentioned owners. The classic small pet store cage provides perhaps 2-3 square feet for animals that naturally range widely and need space to run. Single guinea pig keeping causes loneliness and depression in these intensely social animals - their need for species-specific companionship is not met by human interaction alone. Vitamin C deficiency from inadequate fresh food causes scurvy - painful joint disease and poor wound healing. Dental problems from inappropriate diets cause chronic pain that may go unrecognized for months. The gap between standard pet store advice and actual guinea pig welfare requirements is enormous, and owners who follow typical recommendations may believe their pet is fine while it is actually suffering.
