Intelligent and mischievous, domestic rabbits are the ancestors of the European rabbit. While we love these long-eared critters, we really wish less folks kept them as companions. They rarely get the ideal diet, space, and stimulation required by a rabbit, which is why we do not recommend them as companions for most adults and nearly all children. While many believe that rabbits are great for children, rabbits can be easily injured when mishandled and are capable of biting, kicking, and scratching. They are the third most common domestic species we help.
