Pet rabbits should be fed grass hay (timothy, oat, clove, brome, prairie, and Bermuda) on a free-choice basis. Pelleted food (containing 18 to 24% fiber and 14 to 17% crude protein) should be limited to ¼ cup per 5 pounds of body weight per day maximum. Pellets made from timothy hay may be better for adult rabbits than those made from alfalfa hay. Rabbits should be offered dark leafy greens (e.g., turnip, collard, mustard, and dandelion greens; kale; carrot, beet, and broccoli tops) (wash them first) at a rate of 1 cup per day for a 5-pound rabbit. Also offer clover, parsley, lettuce, cabbage, carrots, strawberries, and apples. Avoid lots of alfalfa (both hay and pellets). Water for drinking should be available at all times.
