Rabbits are a type of mammal in the order Lagomorph, a group that also includes hares and pikas. Despite popular misconceptions, rabbits are not rodents. There are at least 30 species of rabbits on the planet and more than half of the world's population are found in North America.
Rabbits vary in size depending on species, with a length from 8 to 20 inches and a weight from less than a pound to over 4 pounds. As of 2015, the world's largest rabbit was over 4 feet long.
Like other mammals, rabbits have fur, are warm-blooded and give birth to live young. They all have long ears and large feet. Rabbits are herbivores, meaning they eat plants. They often spend their time grazing on grass and other ground vegetation.
Rabbits live in forests, fields and urban areas. Some species also burrow into the ground. They are social creatures, living in groups called herds in a warren.
Kits or kittens are the proper name of young rabbits, whereas the adult males are called bucks and the females does. Rabbits are prolific breeders, giving birth three or four times in a single year, making them a nuisance to some farmers and gardeners. The kittens are born blind and without fur.
