Do rabbits have nits?

no but they can get fleas so cheak your rabbit regularly by buying a special flea comb that you can buy in most pet shops for a cheap amount of money and if your rabbit has got fleas then go to a pet shop or local veterinary surgery and buy him/her some drops to put on your rabbits neck and the fleas should all die and you should also buy some spray for your house to kill them in your house if you have had your rabbit in your house .
