Rabbits are members of the order Lagomorpha, commonly called lagomorphs. The domestic rabbit, Oryctolagus cuniculus, is descended from wild rabbits of Europe and northwestern Africa. There are many different breeds of domestic rabbits, ranging from the diminutive Dutch and Polish breeds weighing from two to four pounds to the large breeds like the Giant Chinchilla and Flemish Giant, weighing up to 14-16 pounds. Rabbits make good pets and can be house trained. Females are called does and males are referred to as bucks.
Older bucks and some does that have given birth to a litter of kits (baby bunnies) develop strong territorial instincts and may bite people, but usually only if provoked. Rabbits can also inflict painful scratches if improperly restrained or if naturally aggressive. Some breeds are more aggressive than others, with Dutch rabbits being more aggressive than New Zealand Whites and Lops. Rabbits thump using both hind limbs as an isolated response to a fearful or painful situation. Rabbits begin approaching sexual maturation when older than three months (depending on the breed, nutritional status and health) and at that time, they may begin attacking each other. So, once they reach that age, they should usually be housed individually. In some circumstances, female groups established before sexual activity begins may be housed together. Mature rabbits should only be paired at mating. Neutering will usually decrease aggression.
