Does your guinea pig get enough vitamin C? Build a day's greens

Guinea pigs can't make their own vitamin C, so it has to come from food every day. Here is where it comes from (hay, fresh pellets and vitamin C-rich veg), which vegetables help most, and which foods to avoid.

Tap the veg you offer in a day to see a rough vitamin C total for your pig, and learn when to ask a vet instead.
