In the wild guinea pigs eat a wide range of grasses, weeds, bugs, seeds along with fruit. It is important to remember that Guinea Pigs are often mistaken as herbivores, but they actually indeed omnivores and therefore they do need protein in their diet to keep them in good health. Guinea pigs should ideally be fed twice daily, both in the morning and then again in the evening. Here at GJW Titmuss we offer a good selection of Guinea Pig food from top brands such as Supreme, Allen and page and Burgess. These brands all include Vitamin C in the formulation as guinea pigs cannot create their own and will become ill without it. Hay should also be included in their diet, as it provides fibre to aid digestion and helps to wear down their continuously growing teeth.
