While introducing a new food to your guinea pig, gradually mix Sunburst with your pet%s old diet. Increase the amount of Sunburst over a period of 7 to 10 days. This will allow your pet to adjust to the new food and it will prevent any upset to your pet's digestive system. Feed your guinea pig ¬ to 1 cup of Sunburst per day depending on the age of your guinea pig. Always regulate the food portion to maintain your pet's weight and if feeding multiple guinea pigs. A pregnant or lactating female will sometimes eat 2 to 3 times as much as a normal adult. Guinea pigs require vitamin C, which is found in a stabilized form in our food; however, the potency of the vitamin C will decrease if food is not properly stored. It is important to store food in a dry, sealed container in a temperature-controlled location away from the light. Remove and discard uneaten food everyday and clean bowl prior to refilling it. Always maintain fresh drinking water near your pet's food container.Store in a cool, dry place free of insects and humidity. Refrigerate for extended storage.
