Rabbits in the context of "Cainotheriidae"

Hares and jackrabbits are mammals belonging to the genus Lepus. They are herbivores and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears that dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret".

Members of the Lepus genus are considered true hares, distinguishing them from rabbits which make up the rest of the Leporidae family. However, there are five leporid species with "hare" in their common names which are not considered true hares: the hispid hare (Caprolagus hispidus), and four species known as red rock hares (Pronolagus). Conversely, several Lepus species are called "jackrabbits", but classed as hares rather than rabbits. The pet known as the Belgian hare is a domesticated European rabbit which has been selectively bred to resemble a hare.

Hindgut fermentation is a digestive process seen in monogastric herbivores (animals with a simple, single-chambered stomach). Cellulose is digested with the aid of symbiotic microbes including bacteria, archaea, and eukaryotes. The microbial fermentation occurs in the digestive organs that follow the small intestine: the cecum and large intestine. Examples of hindgut fermenters include proboscideans and large odd-toed ungulates such as horses and rhinos, as well as small animals such as rodents, rabbits and koalas.

In contrast, foregut fermentation is the form of cellulose digestion seen in ruminants such as cattle which have a four-chambered stomach, as well as in sloths, macropodids, some monkeys, and one bird, the hoatzin.

A petting zoo (also called a children's zoo, children's farm, or petting farm) features a combination of domesticated animals and some wild species that are docile enough to touch and feed. In addition to independent petting zoos, many general zoos contain a petting zoo.

Most petting zoos are designed to provide only relatively placid, herbivorous domesticated animals, such as sheep, goats, rabbits, ponies and donkeys to feed and interact physically with safety. This is in contrast to the usual zoo experience, where normally wild animals are viewed from behind safe enclosures where no contact is possible. A few provide wild species (such as pythons or big cat cubs) to interact with, but these are rare and usually found outside Western nations.

Boreoeutheria (/boʊˌriːoʊjuːˈθɛriə/) is a magnorder of placental mammals that groups together superorders Euarchontoglires and Laurasiatheria. The clade includes groups as diverse as giraffes, pigs, zebras, rhinoceroses, dogs, cats, rabbits, mice, bats, whales, dolphins, and primates (monkeys, apes, and humans).

With a few exceptions, male boreoeutherians have a scrotum, an ancestral feature of the clade. The sub-clade Scrotifera was named after this feature.
