"This is a wonderful food! It has plenty of vitamin c which guinea pigs need. I used to buy my two girl guinea pigs Cinnamon and Ginger a pellet with tons of "extras" but they would always pick and choose what to eat. This is a plain pellet, but they love it! A tip: mix in some Kaytee Healthy Toppers, which is just some dried fruit that adds some fun to their diet. Great Product!"
