with my rabbit, when he was a baby (under 1 year) i let him free feed rabbit pellets. but when he was around 1 year old i limited his pellets to 1/4 cup a day otherwise he would become obese from eating all the rabbit pellets. some rabbits can free feed pellets and some need to have a limited amount. some people don't give their rabbits pellets, just timothy hay as their main food source. *your decision*
my rabbit and all rabbits should have a limited amount of timothy hay because it is crucial to their digestive system. they will become sick without it. *necessary*
they should have limited water supply. i use small animal water bottles and when they are empty i refill them. some people like to use heavy ceramic bowls (like for dogs or cats) and have their rabbits drink right out of the bowl. both ways are fine.
*necessary*
every day i give my rabbit a piece of papaya as a treat because it is good for them. *optional*
you don't need to give him/her baths (they bathe themselves) but unless something happened where they become dirty or get poop/pee on them, you can give them a bath with rabbit shampoo but otherwise they don't need to be bathed, it is usually very stressful for them
their nails and dewclaws need to be clipped and kept maintained otherwise the vein in the nail will keep growing along with the nail and it will cause many problems with the rabbit if the nails get really long. "necessary*
rabbits teeth are constantly growing so you need to get hard toys for them to chew on. i use apple tree sticks which keep my bunnies teeth down. other toys work too but i l personally like using wood sticks that are made for rabbits. *necessary*
a rabbit should always have time out of their cage for exercise. every day i let my rabbit run around outside of his cage in my room with me supervising him about an hour or more. sometimes i'm busy so he comes out every other day or just for a little bit each day. watch because they chew everything!!! *necessary*
you can also litter box train rabbits. many people do this because it is easier to clean the cage and they don't have to worry about the rabbit going to the bathroom all around their house when he/she is running around getting exercise. *optional*
i don't give my rabbit any vaccinations unless something happened like a health problem where he needs medical attention from the vet. just like most animals, if your rabbit acts different, stops eating/ drinking/ pooping i'd seek a vet
another thing, it is a good idea to get your rabbit neutered or spayed. it helped my rabbit with his moodiness and when he had some feelings for my cat
rabbits need a lot of care and are high maintenance. but if you take care of them, clean their cage, and love them and spend time with him/her they are a fun and loving pet
if you have anymore questions that i didn't answer, feel free to ask. that's what we are here for
hope this helps!!! i think i covered mostly everything
