Cat anatomy

Cat Anatomy refers to the physical structure of the domestic cat, a member of the family Felidae. Cats have evolved as predatory animals with adaptations that aid them in hunting and catching prey.

Skeletal System

The skeletal system of a cat consists of 230 bones, which are highly adapted for agility and speed. The cat's skeleton is lighter than that of a similarly sized dog, which allows for greater flexibility and agility. The cat's skull is unusual among mammals in having very large eye sockets and a powerful and specialized jaw.

Muscular System

The muscular system in cats is highly developed and supports the cat's agile movements and flexible body. Cats have a clavicle, or collarbone, that does not connect with other bones but is buried in the muscles of the shoulder region. This allows the cat to extend its stride length and flexibility.

Digestive System

The digestive system of a cat is adapted for meat-eating, with a simple stomach and a short intestine. Cats have a higher protein requirement than many other mammals and are unable to digest plant material efficiently.

Respiratory System

The respiratory system of a cat includes the mouth, nose, trachea, and lungs. Cats have a unique structure in their lungs, called the feline lung, which allows for a greater surface area for gas exchange.

Circulatory System

The circulatory system in cats includes the heart and blood vessels. The cat's heart is similar to that of other mammals, with four chambers. The cat's blood vessels are also similar to those in humans.

Nervous System

The nervous system in cats is responsible for coordinating their senses and motor functions. The cat's brain is highly developed and is more similar to a human brain than to a dog's.

Reproductive System

The reproductive system in cats is typical of mammals, with the female having two ovaries and the male having two testes. Cats are seasonally polyestrous, which means they may have many periods of heat over the course of a year.
