Review on Premium Timothy Naturals Guinea Pig Food: Made in USA, with Added Vitamins & Minerals and Timothy Hay (3.5 or 5 lb) by Michael Zambrano

A guinea pig is unlikely to care what pellets it ate, but mine does. I bought a cheap brand from a department store and they didn't actually eat it. I buy this brand because they make animal feed for the zoo and I think they are good at animal nutrition and don't try to make cheap feed. Don't forget to feed your pigs vitamin C. As good as this food is and fortified with vitamin C, vitamin C breaks down quickly in processed foods. All guinea pigs need an additional source of vitamin C. DVM.
