Your pet should be fed free choice, that is access to food at all times, from a clean, dry bowl that is either in the cage or in a “through the wall” feeder that can be filled from outside the pet’s home. Always maintain a fresh supply of water that is accessible continuously. Should your pet’s food become contaminated with urine, droppings or water, discard the soiled food, wash out and dry the dish and replace with a fresh supply. Although supplementation is not necessary, you may want to occasionally give your Guinea Pig a treat, such as a seed stick, carrot, or one of many other prepared treats on the market.
