Hello! It's so great to hear that you may be getting a rabbit! I love rabbits so much, one of my favorite animals. I'll try to help you as best as I can. For small-medium sized holdable rabbit, I would get a smaller breed anywhere between a mini rex (which I find are very good with handling, I had one before that would even let you hold her up while she floated on her back in the bathtub water lol) or a mixed dwarf. Netherlands are very small and cute but I've seen some that can nip or not like being held.

Most rabbits though are skittish at first, ecspecially if you get one that hasn't been around humans much. It would be best to find one that has been around people and been handled before. The longer you have your rabbit and gain its trust though handling it, the better it will be with letting you hold it. So far my rabbit has never once tried to bite me (she is a dwarf/rex mix) and she lets me hold her very well. Some rabbits just have a personality that they don't like to cuddle. And then some do It really depends on how much time you spend with it.

Yes, Bunnies love carrots and carrots can be good for them, but only in small quantities. If they are fed too much carrot, their poo can turn to diarrhea which is very bad for bunnies to get. Ecspecially slowly introduce carrots if they rabbit is still a baby between 4-6 months. Rabbits also should always have hay available to them, the best kind of hay for them is a mixture of Timothy and Alfalfa hay (aka Farm hay) and rabbits can also have pellets too, although pellets are not needed. My rabbit loves pellets and I give her a good brand called Martin (which also is suppose to reduce the smell of their urine). Rabbits can eat alot of vegetables, but not in major quantities, for instance green veggies should be fed in little amounts or else they will get diarrhea because they have such sensitive stomachs. I can't really think of any veggies not to feed rabbits at the moment. Buttercup will be good at that one

Dont' feed a rabbit milk (lol I will say that much about what not to feed)

Well that's all I can think of right now. Also once the rabbit is between 5-6 months it is best to get it spayed/neutered. Rabbits gets cancer once they get a certain age because of their urinary track which is why alot of rabbits die at the ages of 2-5, which most bunnies can live to be 10-15 if they are spayed/neutered and well looked after

Well I hope I helped you! And if you get a bunny you should so show us some pictures! Rabbits are too cute! Best of luck with your bunny!
