The modern day rabbit needs a very simple diet. According to Wikipedia, the bulk of the domestic rabbit’s diet comes from Timothy-grass, otherwise known as Timothy-hay, and other hays. Hay in combination with pellets and vegetables is the perfect combination of food for your pet rabbit. According to the House Rabbit Society, pellets should be reduced in a rabbit’s diet as he matures and when fed to him should be fresh, within six weeks of purchase.
Vegetables should be plenteous in your pet rabbit’s diet. Look for a variety of dark leafy vegetables such as kale and other veggie roots, such as carrots. As you reduce the amount of pellets on the menu, you should also increase the availability of hay and vegetables to make up for the calories lost. A small amount of fruits are okay to feed rabbits as well. Always, always keep plenty of fresh water available for your bunny. Thank you to the House Rabbit Society for the following recommended foods list.
