Changing Food Brands
When you change a rabbit's food brand or diet, you should—like with most animals—take it slowly and mix the new food with the old food. This helps their digestive system get used to the new diet.

TREATS
Bananas make excellent bunny treats, as do nectarines, apricots, peaches, melons, apples, cherries, berries, graps, pineapple, carrot, cucumber, celery, and DARK lettuce--NOT iceberg. Iceberg lettuce, cabbage, any meat/fatty product is bad for bunnies.

NOTES
Plants that grow from bublbs are toxic to rabbits.
