Your rabbits' diet plan should include clean water and at least one bundle, about the size of your pet, of high-quality hay per day. On the side, you can also provide a controlled portion of leafy greens and commercial pellets. An adult-sized handful of washed, dark leafy greens and between one or two egg cups of pellets a day depending on your pet's size is appropriate. Plus, your rabbits' should have access to growing grass for grazing. Additionally, the occasional small amount of carrot or apple can also be given as an occasional treat! Rabbits must have an adult-sized handful of safe washed leafy green vegetables, herbs and weeds daily.
