Rabbits are not not the cuddly pets that you see portrayed on social media. As they are prey animals they do not like being picked up, cuddled or touched in general and are therefore particularly bad pets for children. They can live 10-12 years and that's a pretty long commitment.
Also, I know that people say that rabbits can be house trained, but never perfectly and there will always be accidents. Even if they could be trained to use a litter tray, the smell would not be at all pleasant in your house.
Also, rabbits need fresh hay daily. They will track that hay through your whole house while they roam, also chewing on skirting boards, door frames, wires, remote controls, walls, furniture and everything and anything else that they fancy.
I have rabbits who live outdoors and keeping their housing clean is a daily task, and I can't even smell them from the house. Trying to keep your house clean and fresh smelling while you house rabbits inside would, I imagine, be a full time job.
Lastly, if all of the above doesn't put you off then please, please, please adopt your rabbits from a rescue centre. They will be neutered / spayed and vaccinated. Rabbits need two vaccinations every year - 1 for RHD and Myxi and the other for RHD2. You will also want to get a bonded pair as not just any rabbits can live together without fighting or breeding. It is notoriously hard to tell the sex of baby rabbits as well and pet shops often get it wrong, so you end up with accidental litters of buns. There are over 70,000 rabbits in rescue centres in the uk. Adopt, don't shop.
Good luck op, whatever you decide.
Ps - there are lots of FB groups for house rabbits, rabbit housing etc etc. I'd definitely advise that you join some of those groups for further research before committing to anything.
