A house rabbit is a domestic rabbit kept as a pet for companionship, who lives inside the home with his owners. House rabbits usually have an indoor pen and a rabbit-safe place to run and exercise, such as a living or family room. They are easily trained to use a litter box and can learn to come when called.
