What and how much does a guinea pig eat?

Guinea pigs eat pellets, timothy hay, a little alfalfa hay, apples, carrots, specific kinds of lettuce, very small quantities of strawberries, and you may be able to feed them things such as extremely small quantities of cooked pasta. You can also feed them treats found at the pet store. Good guinea pig products include Oxbow (Very good), Kaytee and some others.
