Guinea pigs are popular small pets whose welfare needs are often misunderstood, leading to chronic suffering from inappropriate housing, diet, and social isolation.
Guinea pig welfare fails most commonly through three routes: solitary housing (causing chronic loneliness), insufficient space (causing boredom and obesity), and incorrect diet (causing dental disease, scurvy, and gut disorders). These are entirely preventable welfare failures that arise from poor consumer education and outdated pet care guidance still circulating online and in pet stores. Updated welfare information from organizations like the RSPCA reflects significantly higher standards than historical norms.
