Check
http://www.guinealynx.com/healthycavy.html. That should be a great source of info for you! The best food is made by Oxbow (
www.oxbowhay.com). You should feed pigs under a year Cavy Performance, and you should feed older pigs Cavy Cuisine. The best hay I've heard of is
www.kmshayloft.com-- Kleenmama's! My first oder should come in tomorrow, I'm so excited! It's fresher and cheaper by far than the stuff you get in the pet store.
