All carnivores have a prey drive which is their instinctual urge to find, pursue, and capture prey. When it comes to rabbits, if a rabbit just walks up casually to a cat there’s a good chance your cat’s prey drive won’t kick in.
While cats might have an instinctual urge to hunt wild rabbits a lot can change inside the home. Cats and rabbits can get along with the right introductions. Watch out so that a frightened rabbit doesn't trigger your cat’s prey drive!
One of the safest ways to start the introduction is while your rabbit is safe within a hutch or cage. That way the two furry future friends can get used to each other without any real danger between them.
