Feeding
Bunnies will overeat if given the chance. Don't give your rabbit unlimited pellets. He needs only 1/4 cup of pellets each day. Look for high-fiber content (18% minimum) and low protein content (14% maximum) pellets. It is also very important to give your rabbit unlimited amounts of timothy hay. Hay is the most important part of the bunny's diet.

Treats
If you give your bunny veggies and fruits, please do so and introduce it slowly since it can cause digestive problems. Treats should not be fed more than once a day, and may include:

Veggies
Alfalfa
Radish
Basil
Brussel Sprouts
Carrots
Celery (sliced thin to avoid choking)
Dandelion greens
Escarole
Green or Sweet Peppers
Mint
Parsley
Peppermint leaves
Raddichio
Raspberry leaves
Lettuce
Spinach

Fruits
Apples (seeds are toxic-do not feed)
Blueberries
Bananas (not the peel)
Grapes/Raisins
Melon
Watermelon
Orange
Papaya
Peach
Pear
Pineapple
Plums
Raspberries
Strawberries

Water
You can use a water crock or bottle, it's up to you. If you are going to keep the bunny outside in the winter, a crock might be better. Make sure the crock or bottle remains clean and the bunny has fresh water at all times.

Litter Training
To litterbox train your rabbit, start by putting the box in the area of his cage that he usually uses for elimination. Place a few droppings or a piece of newspaper with the rabbit's urine in the box so he recognizes his scent. Add timothy hay to the box to entice him to jump in and eliminate while eating. Start by keeping the bunny and the box in the cage, and gradually increase his space as he masters using the box. It is a good idea to put out numerous litterboxes while is he learning.
Fill the box with a non-clumping, non-toxic litter such as hay, shredded newspapers, or recycled newspaper litters such as Carefresh or Yesterday's News. Avoid using clay cat litters, cedar, as these products can cause health problems in your rabbit.
