My family owns two cats, and all of my rabbits get along with them pretty well. I’ve never had problems with them but if your cats tend to be a little wild, I’d suggest slowly introducing them (put a rabbit in a place it feels save and let the cat (one at a time) smell them). Correct the cats if they bat at the rabbit, etc.
Since their kittens I don’t except them to be anything but curious. Start to build a bond as the kittens are still young
