I have 5 INDOOR house bunnies. They might get to go outside 3 times a year under strict supervision and only then in a pen. There are just too many predators...kids, dogs, hawks... Occasionally I feel guilty about it but the secret with bunnies is that the more attention you give them, the more they turn into these really great friends. Bunnies kept in barns or outside cages don't get near enough attention and don't really develop their personalities or turn into loving companions. There are a few exceptions. I also volunteer at a rabbit sanctuary and some of the bunnies crave human companionship but most are leery. Buns can be litter-box trained and can also be destructive so it's vital to bunny-proof their living area but it is well worth it. They are truly great companions.
