The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, and carnivorous mammal. They are often called housecats when kept as an indoor pet or simply cats when there is no need to distinguish them from other felids and felines. Cats are often valued by humans for companionship and their ability to hunt vermin.
Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. They can see in near darkness. Like most other mammals, cats have poorer color vision and a better sense of smell than humans.
The Maine Coon is among the largest domesticated breeds of cat. It has a distinctive physical appearance and valuable hunting skills. It is one of the oldest natural breeds in North America, specifically native to the state of Maine, where it is the official state cat.
Although no records exist regarding the Maine Coon's exact origins and date of introduction to the United States, there are multiple competing theories. The breed was popular in cat shows in the late 19th century, but its existence became threatened when long-haired breeds from overseas were introduced in the early 20th century. The Maine Coon has since made a comeback and is now one of the most popular cat breeds in the world.
The Sphynx is a breed of cat developed through selective breeding starting in the 1960s, known for its lack of a coat (fur), though it is not truly hairless. The skin should have the texture of chamois, as it has a fine layer of down. Whiskers may be present, either whole or broken, or may be totally absent. The skin is the color their fur would be, and all the usual cat marking patterns (solid, point, van, tabby, tortie, etc.) may be found on Sphynx skin. Because they have no coat, they lose more body heat than coated cats. This makes them warm to the touch as well as heat-seeking.
