Rabbit pellets are a specially formulated, concentrated food for rabbits that provides essential vitamins, minerals, and fiber, forming the base of a rabbit's diet, especially for young rabbits. A high-quality pellet is typically made from ground hay, like timothy hay, mixed with protein, carbohydrates, vitamins, and minerals, but should avoid seeds, corn, sugar, and animal proteins. While important for growth, the amount of pellets fed to an adult rabbit should be limited to prevent obesity and other health problems, with hay and fresh greens making up a larger portion of their diet.
