Caring for guinea pigs involves providing a spacious cage with proper bedding, such as paper-based or aspen shavings. They need a balanced diet consisting of high-quality hay, fresh vegetables, and specially formulated pellets. Fresh water should always be available, and their living area should be cleaned regularly to maintain hygiene. Guinea pigs are social animals and thrive in pairs or small groups, so consider adopting more than one. Regular handling helps them become friendly and comfortable with humans. Additionally, they require routine veterinary check-ups to monitor their health and prevent common issues like dental problems or respiratory infections.
