Felidae

Felidae is the family of mammals in the order Carnivora that we call cats. Animals in this family are also called felids. They are known for their different fur patterns, claws that can be pulled in, and strong bodies. They are obligate carnivores, which means they must eat meat to live. Most cats hunt alone and wait for or follow their prey.

Wild cats live in many places around the world, such as Africa, Europe, Asia, and the Americas. You can find them in forests, grassy lands, arid areas, wetlands, and even mountains. Some cats are active at night, while others hunt during the day, depending on what they eat.

Scientists group cats into two main subfamilies: Pantherinae and Felinae. Pantherinae includes big cats like lions and tigers. Felinae includes smaller cats such as house cats and ocelots. Our knowledge about these groups changes with new research in molecular biology. The first cats lived during the Oligocene about 25 million years ago. Over time, they evolved into many different species.

Characteristics

All cats in the cat family have some cool traits. They walk on the tips of their toes and have curved claws they can stretch out and pull in. Their bodies are flexible and strong, and their skulls are short with big eyes that help them see well in the dark.

Cats have special whiskers that help them feel their way in the dark and catch prey. Their eyes shine at night because of a special layer that helps them see better. Different cats have many kinds of fur, from spots to stripes, and they can be many colors, from white to black. Some cats, like tigers, are very large, while others, like the rusty-spotted cat, are quite small.

Evolutionary history

The family Felidae is part of the Feliformia, a group that split into different families about 50 to 35 million years ago. The earliest known cats appeared around 35 to 28 million years ago. Fossils of these early cats have been found in places like France and Mongolia.

During the Middle Miocene, around 15 million years ago, a group of cats with long teeth, known as saber-toothed cats, appeared. These cats lived in many parts of the world and were good hunters. Later, big cats like lions and tigers began to appear. Cats eventually spread to South America when a land bridge formed between North and South America. Some of the large saber-toothed cats went extinct around 12,000 to 10,000 years ago, possibly due to changes in the environment and new hunters arriving in the Americas.

Classification

Cats belong to a family of animals called Felidae. Scientists used to sort them into five groups by how they looked. Now they know some of these groups belong to bigger families. One group, called Acinonychinae, used to be separate, but now it is part of the Felinae family.

The family tree of cats shows how different kinds are related. This helps us learn how cats changed over time.
