Cats, belonging to the order Carnivora and the family Felidae, are vertebrate animals.

They have a small body size, ranging in color from bluish-gray to tawny, with a slender build measuring 0.3 to 0.5 meters in length.

Their fur is dense and soft, with small collarbones, short snouts, round eyes, robust necks, relatively short limbs, and several spherical pads on their feet.

The surface of their tongue is covered with filamentous hook-shaped papillae with a keratinized layer. Male and female cats resemble each other, with males having slightly larger heads. Cats have a long reproductive and fertile period, with a lifespan ranging from 12 to 17 years.

Cats have a wide distribution, inhabiting various environments, from tropical rainforests, deserts, and plains to cold grasslands and plateaus, excluding Antarctica. They are solitary animals with a strong territorial instinct, and when threatened, they can be aggressive, displaying exceptional climbing abilities. As predatory animals, they primarily prey on rodents, birds, fish, and other small animals in the wild, showing a preference for meat and exhibiting selective eating habits.

As household pets, cats can alleviate people's psychological stress and fulfill their emotional needs. Additionally, their ability to catch mice significantly reduces economic losses for humans. The cultural significance of cats dates back to their domestication, where they were revered as "sacred animals," often associated with both sun and moon deities in ancient Egyptian art.
