Mostly Romaine and Celery. Little Rabbit gets about a half a cup, the baby eats until he's full, which is never and about two cups later, and the other big rabbit eats about a cup. They get this morning and night. They also get parsley, cilantro, and mint. Little rabbit likes Belgian endive and gets it occasionally as it's so expensive stateside. They also get banana chips, peel, raspberries, and craisins as treats. Little rabbit also gets cheezeits, doughnuts, cereal bars, zebra cakes, popcorn, garbage. Have to be really careful what you leave out around her.
