EMERAID Sustain Herbivore is highly digestible nutrition scientifically designed for herbivorous mammals (rabbits, guinea pigs, chinchillas, and more) and herbivorous reptiles (green iguanas, tortoises, and more) who are recovering from critical illness, suffering from chronic medical conditions, or being underweight. It’s also a transition diet for herbivores moving from intensive care nutrition to normal food. The powdered formula is mixed with water to feed and can be fed in six easy ways: in a bowl, as a food topper, HDN bites, through a syringe, as a gravy or use through an e-tube.
