Introducing a second rabbit to the home is not always easy. For the best chance for success, both rabbits should be neutered adults of opposite sex. Introduce them for short periods in an area unfamiliar to both rabbits. Be aware that fighting may occur, especially from the resident rabbit. It is best to get help with these introductions from someone experienced with rabbits.
