Cats and rabbits get along well because cats think grooming someone is dominant, but rabbits think being groomed is dominant, so they both think they're on top.
Domestic rabbits are the most attitude-y animals I've kept, with such surprisingly variable personalities.
I had a rabbit that we'd let out in the garden, and if the neighbour's cat came in the garden, the rabbit would chase it out, and even attack it if it wouldn't leave.
