Just because a pet is small and doesn’t need daily walks doesn’t guarantee it is low maintenance. Take guinea pigs, for example.

Sweet and cuddly, guinea pigs can make wonderful pets for adults or children over the age of 6. But grown-ups should always supervise handling and daily care to prevent injuries, check for abnormalities and ensure good nutrition and hygiene.

A guinea pig’s daily diet ideally includes hay, pellets and fresh veggies, especially those rich in vitamin C. Between feeding and cleaning dirty bedding, daily pet-related chores take time. The cost of food and bedding adds up too. And while they don’t require vaccinations, guinea pigs need routine veterinary examinations just the same.

If you’re still game for a guinea pig-sized commitment that lasts five to seven years, check out your local animal shelter for these cuties.
