I have 3 cats and a bun, we were surprised that the cats have no interest in eating the bun, they just get bothered when he gets too in their face/occasionally tries to hump them. We do not have the most well behaved bun...he also when left to his own devices will eat kitty food and kitty litter...which is why he stays upstairs while the cat space is downstairs. The bun lives in our bedroom, he's got a small animal play pen (about a 4x5 foot space) that we lock him up in at night so the cats can snuggle with us, the bun get to free roam the bedroom from 7 AM to 9PM roughly every day.
I will say my cats and bunny did have a much better relationship, but then we moved to a new apartment and the bun tried to become much more dominant of the cats...he never tried to hump the cats before we moved. I don't know what your situation is but know that things can change if you intend to move.
You can start with supervised meetings-no more than 15 minutes i'd say-with you watching your cat and being very close and ready to snatch them up if they act even the least bit predatory (watch their eyes for dialated pupils, getting low to the ground and the telltale butt wiggle indicating that they are going to pounce). If nothing like that happens then just see how it goes after a few visits, they could be friends, or they may not seem to care about one another's existence. Still I personally would never suggest leaving your cat unsupervised with the bun. While I don't think my cats would hurt the bun I still appreciate that they are predatory creatures with instincts that could kick in, or they could just rough house a little too rough. Either way it doesn't go well for the bun.
