Welcome! We would love to see photos of your new rabbit.
If you’re transitioning him to becoming a house rabbit, I start with him being in restricted areas so as not to overwhelm him. Are you planning to use a hutch/cage/pen or other for him?
Did your friend line his hutch with bedding or hay? That might be a reason why he chose the “bedroom” area as the toilet…
My question is, how should I go about litter training a rabbit who is 2 years old and tosses the litter pan like a ragdoll every time it is presented?
Lol.
Firstly, avoid using any other bedding material in his habitat. You’ll only want litter-like material in the litterbox. Go large for a flemmie! Something like an under bed storage box. He may take to sleeping in it too but some rabbits just do.
A trick I saw from another member years ago was to anchor one box down, then place a second box inside it as the removable litter box. They had glued a regular cat box down in the rabbit condo. You might be able to secure one by putting a few holes in the side and fixing against habitat side with zipties. Or use a heavier wooden crate that you can place plastic try in. Using a safe wood as it’s more then likely going to get chewed!
For litter training, place his hay in the box on top of the litter or in a rack above the box. Keep the space he is in small at first, then increase this over time. Im meaning the space he will be in the majority of the time. He could certainly have a run about the house or outside for daily exercise. He may have a tendency to mark with territorial poop in the beginning. This usually self resolves once they feel a place is sufficiently marked.
And is it worth it for me to get him neutered at his age? Will it make him less likely to spray? Less likely to mount things?
Is he currently doing this? How long have you had him now? Do you have other rabbits or pets? It might be due to his being in a new environment and resolve with time.
He’s certainly not too old to get desexed and it could help with some of those behaviours. He may have some ingrained habits but neutered rabbits have less smelly urine which is a bonus. Plus, if you think you might get him a friend, his being neutered will work in your favour.
And could I ever bond him with another rabbit? Should it be male or female if I can?
Yes, I think you could. Bonding really comes down to the nature of the rabbits, their history and how much work you want to put into it. Sometimes it can take a bit of work to achieve a bond, sometimes it’s a breeze. Usually opposite sex pairings are the easiest, but that is not a firm rule. Again, it depends on the rabbits. A lot or rabbit rescues let you bring you desexed rabbit in to meet some others. It can give an idea which ones will likely get along best.
HTH.
