Cats are common pets throughout the world, and their worldwide population as of 2007 exceeded 500  million. Due to its ability to thrive in almost any terrestrial habitat, it is among the world's most invasive species. In addition to the general guide, there are specific guides for proper grooming, common feline diseases, and behavioral issues.

Domestic cats have been diversified by humans into breeds and domestic and wild hybrids. Cat food can be formulated for adult maintenance (intended for healthy adult cats), growth and reproduction (for kittens and pregnant or lactating females), and all life stages. Pet, stray, and feral cats (stray and feral cats are community cats) are all this same species, which we call the domestic cat.1 Cats, also called domestic cats (Felis catus), are small, carnivorous (meat eating) mammals, of the family Felidae. Volunteers continue to feed and give care to these cats throughout their lives, and not only is their lifespan greatly increased, but behavior and nuisance problems, due to competition for food, are also greatly reduced. The average lifespan of such feral cats is much shorter than a domestic housecat, which can live sixteen years or more.

Outdoor cats are prone to infections from other animals, can get into fights, may be attacked by predators, or may get run over by vehicles. Domestic cats lack a pedigree lineage, while purebreds have one. The Cat Group highlights serious welfare concerns relating to the keeping of hybrid cats as pets, and of hybrid cat breeding practices.

This may be a concealed hunting site such as a tree branch, for domestic cats to pounce upon prey. Female domestic cats can have kittens from spring to late autumn in temperate zones and throughout the year in equatorial regions, with litter sizes often ranging from two to five kittens. Indoor cats do best on a well-balanced, weight-management cat food, as they tend to live a less energetic lifestyle due to boredom.

• As long as they are not competing for limited food resources, they can form close-knit groups that are usually composed of the mother cat and her kittens and related females.

By a feline’s second year, he or she is the equivalent of age 24. The Invasive Species Specialist Group has put the cat on its list of the "World's 100 Worst Invasive Species" (ISSG 2007). In some places, especially islands that have no natural carnivores, they have been very destructive to native species of birds and other small animals. In 1871, the first cat exhibition was held in the Crystal Palace in London (Siegal 2004).

They are at least as intelligent as dogs, but they are not pack animals. At that stage they have blue eyes, but not the best sight. In the wild, leaving a scent is risking a dangerous encounter with other animals.

Like other domesticated animals, cats live in a mutualistic arrangement with humans. Because domestic cats are crepuscular hunters, they need only one-sixth of the illumination levels humans require to see well. Compared to other felines, domestic cats have narrowly spaced canine teeth relative to the size of their jaw, which is an adaptation to their preferred prey of small rodents, which have small vertebrae.

Like all members of family Felidae except the cheetah, cats have retractable claws. Domestic cats are considered to be descended from the wild cat Felis silvestris, which is found naturally over much of Europe, Asia, and Africa, and which is one of the smaller members of the cat family. Due to the way that fur color is passed down through genetics, almost cat all calico-colored cats are female.

The domestic cat has slit pupils, which allow it to focus bright light without chromatic aberration. The domestic cat genes MC1R and ASIP allow color variety in the coat. The domestic cat has a smaller skull and shorter bones than the European wildcat. Their rigorous grooming habits and instinct to bury their bodily waste make them generally much less messy than other domesticated animals. During domestication, cats have undergone only minor changes in anatomy and behavior, and they are still capable of surviving in the wild. This line of a partially domesticated cat left no trace in the domestic cat populations of today.

Inconsistency in a breed's classification and naming among registries means that an individual animal may be considered different breeds by different registries (though not necessarily eligible for registry in them all, depending on its exact ancestry). Many such breeds are recognized by various cat registries. Large sized felines and pantherines only emerged during the Pliocene epoch, including the modern big cat genus Panthera. This is about 20 million years later than the bears and the false saber-tooth cats, and about 10 million years later than the canines. The earliest cats probably appeared about 35 to 28.5 million years ago.
