Description : I just got three guinea pigs (we're fostering them), they seem to like celery, carrots and strawberries. Is there anything else they really like? Or don't like? I heard they are lactose intolerant, is that true?
Last Answer : The most important food for guinea pigs is hay, timothy or meadow grass, as it contains the fiber they need and they enjoy it best. There's a long list of foods to avoid - potatoes, avocado, ... are weaned, milk and other dairy products can give them problems and should not be part of their diet.
