Can guinea pigs eat apples safely?

Guinea pigs can safely eat apples. Because apples are acidic and contain natural fruit sugars, they should be fed infrequently and in small amounts. An appropriate portion is one slice of apple once or twice weekly.

Guinea pigs can eat many fruits and vegetables in addition to apples. Other safe foods for guinea pigs include bell peppers with the seeds removed, romaine lettuce, cucumbers, zucchini, pears and carrots. Oranges are safe when fed once weekly or less because of their high acid content, while celery is safe only when cut into small pieces first to remove the risk of choking on the strings.
