I own a neutered rabbit and he and my cats play and snuggle together. I occasionally foster guinea pigs for our rescue facility (the director is highly allergic to them) and my cats would do anything to eat the lil pigs.. I think you'll be fine. Keep a spray bottle near the rabbit cage for the first week or two, if you think the cat's are stalking the rabbits then stop them with that or however you see fit to discipline them. Remember, positive reinforcement can go a long way. If your cats are being good to the rabbits then play with them or give them a treat.. Don't feed them in sight of the rabbits either, they might associate the rabbits with food, and with that prey drive you don't want the wrong associations to take place..I am planing on breeding rats and maybe mice for snake food and was interested in feeding them to my cats. My concern is that I have 2 small rabbits that live with the cats so I am worried that the cats might start thinking that the rabbits are food.
