We have an elderly guinea
"We have an elderly guinea pig who requires supplemental feeding besides the usual hay and pellets. We mix this Critical Care Herbivore with ground up pellets and water and a touch of unsweetened apple sauce in a bowl for him. He still eats regular food, too, so this blend just aids in keeping some weight on him and helps make sure he is getting more nutrients. We have also used Critical Care with a different guinea pig who was very ill - in that case we used the Critical Care as per the directions on the bag - all Critical Care, no ground up pellets, since in that case the piggy needed all the intense nutrition. In both cases the Critical Care has been very helpful and easy to mix up."
