Feed your chinchilla a diet rich in farm-fresh alfalfa with Oxbow Essentials Chinchilla Deluxe Chinchilla Food. Like other herbivores, chinchillas require daily fiber found in hay to maintain a healthy digestive system. In fact, hay should make up 75 percent of their diet. Oxbow Essentials Chinchilla Deluxe Chinchilla Food is an alfalfa-based pellet that is specifically designed to meet the unique nutritional needs of chins. Along with succulent alfalfa, it contains a blend of stabilized nutrients including Vitamin C, Vitamin E and Vitamin B12 for overall health. Feed young chins under a year old an unlimited amount of pellets and pair with an unlimited supply of grass and alfalfa hay. Adult chins should be fed 1/8-1/4 cup along with unlimited grass hay. Alfalfa hay should only be fed as an occasional treat.
