Cavalier King Charles Spaniel
A breed of small dog developed in the early 20th cent. from the English toy spaniel. It stands about 12 in. (30 cm) high at the shoulder and weighs from 13 to 18 lb (6–8 kg). Its long, silky coat may be slightly wavy, but never curly, and forms a fringe of longer hair, or feathers, on the ears, legs, tail, and feet. Although it is usually white with chestnut markings, it may have any of the color patterns of the English toy spaniel.
Guinea Pig
The guinea pig is the domesticated form of the cavy, Cavia porcellus, a South American rodent. It is unrelated to the pig; the name may refer to its shrill squeal. Guinea pigs were raised by the Incas and have long been used as food in South America. They were first imported into Europe from Guiana in the 16th cent.
Polar Bear
A large white bear, Ursus maritimus, formerly Thalarctos maritimus, of the coasts of arctic North America. Polar bears usually live on drifting pack ice, but sometimes wander long distances inland. They are powerful swimmers and may cross 20 to 30 mi of water at a time. The polar bear’s body is long and streamlined, with a long neck and small head. Adult males are 7 to 91/2 ft (210–290 cm) long, stand 4 to 41/2 ft (122–137 cm) at the shoulder, and weigh 700 to 1600 lbs (320–730 kg). Females are somewhat smaller.
Rabbit
Rabbit is a name for herbivorous mammals of the family Leporidae, which also includes the hare and the pika. Rabbits and hares have large front teeth, short tails, and large hind legs and feet adapted for running or jumping. In most, the length of the ears is considerably greater than the width. Although usage varies, the term rabbit generally refers to small, running animals, with relatively short ears and legs, which give birth to blind, naked young, while hare refers to larger, hopping forms, with longer ears and legs, whose young are born furred and open-eyed.
Squirrel
The squirrel is a small or medium-sized rodent of the family Sciuridae, found throughout the world except in Australia, Madagascar, and the polar regions; it is applied especially to the tree-living species. Tree squirrels range from the size of a mouse to the size of a house cat and vary greatly in color; some Asian tree squirrels are brilliantly patterned. In addition to the tree squirrels, the family includes the ground squirrel, chipmunk, marmot, woodchuck, prairie dog, and flying squirrel.
