Rabbits should get unlimited timothy hay, grass hays, and oat hay (several handfuls, replenished twice a day at least). Keep rabbits cool. It’s best to offer both a water bottle and a crock dish for backup.
Most rabbits need an enclosed space to make them feel secure and prevent chewing on things you don’t want them to chew, so a 30” high dog exercise pen indoors with a litterbox in a is an excellent home. Provide a large soft sheet or rug under the cage, and add grass mats to chew. It should be a good ten times the size of the rabbit. Offer a covered box, or cover part with a towel for privacy. Rabbits are most active at dawn and dusk, and they prefer to sleep in the afternoon. Give them that time to rest.
Feed fresh vegetables at least once a day for rabbits over 3 months: start small, like a pile the size of the bunny’s head (i.e., fresh wet carrot tops, Italian parsley, dandelion greens, cilantro, romaine lettuce). Remove if not eaten in a few hours.
Baby carrots—limit to 3 a day. As they can handle greens, then they can have a handful morning and night.
Babies up to 7 months need unlimited plain pellets and hay. After 7 months, begin to limit pellets to morning/night and increase hay (western timothy, orchard, oat hay). Give huge handfuls of fresh hay, twice a day.
Fruits are treats! Serve only a one inch max (1”) fruit treat every other day or omit! No seeds, corn, onion, nuts, crackers, cereals or sweet treats.
Litterboxes should be big enough for the bunny to get in and turnaround easily, as well as have the front half filled with hay; they enjoy eating in their box, so placing hay in a corner of the box is a good idea. Change the litterboxes once a day or every other day. Do not use cat litter. Use Carefresh or other organic or paper-based litters, newspaper, straw. Keep the litterbox in sight of the bunny at all times, even when out. You may need more than one if your rabbit is out in a larger area.
