The first thing we need to remember about the diet of a guinea pig is that their origin is the South American Andes. Their diet consists of vegetation, and that is mostly grass. In the wild they drink very little water and get most of their moisture from the food they eat. I have so far not found any material showing any studies of their life span or the common causes for fatality in this environment. Our domestic guinea pigs are vegetarians, and should be fed a diet based on this information first. This means that cat food and dog food are not recommended food items for a guinea pig.
