Can rabbits use a pet door? Yes, there are rabbits who use pet doors, but it may take some training. Make sure you choose a door of an appropriate size, and that it opens easily. Of course, the door should lead to a safe area your bunny can’t dig out of, and where predators can’t get to them. Try enticing your bunny to go through the door with a tasty treat. Never use force – you don’t want your pet to associate the door with anything bad, just with the wonders available on the other side.
