Acinonychinae used to only contain the genus Acinonyx but this genus is now within the Felinae subfamily. With their large upper canine saber teeth, they were adapted to prey on large-bodied megaherbivores. In the Early Miocene about 20 to 16.6 million years ago, Pseudaelurus lived in Africa.

Kittens are weaned at between six and seven weeks, and cats normally reach sexual maturity at 5–10 months (females) and to 5–7 months (males). The gestation period for cats is about two months, with an average length of 66 days. A female cat may mate with more than one cat when she is in heat, and different kittens in a litter may have different fathers. Several male cats may be attracted to a female cat in heat. However, cats are naturally curious, so some domesticated cats may get into some mischief.

Throughout all this time, cats were allowed to come and go freely from human householdseven President Calvin Coolidge’s cat had free rein to wander to and from the White House during the 1920s. In 2023, pet cats lived for around 13 years. In 2021, there were about 220 million pet cats and 480 million feral cats in the world. However, many cats live well into their golden years, with an average lifespan of years old. If we think like a cat, here’s how a cat’s age compares to a human’s.

Community cats deserve to live their lives outside just as they have for thousands of years. Until spaying and neutering pets became available and accessible around the 1930s, keeping intact cats indoors was messy business during mating season. With the invention of cat litter, cats rocketed to popularity as indoor pets, but their outdoor survival skills remain.9

• The curved claws may become entangled in carpet or thick fabric, which may cause injury if the cat is unable to free itself.
• The earliest known association between cats and humans likely dates to the origins of agriculture in the Middle East, about 15,000–10,000 years ago.
• The more we understand cats, the better we can care for them.
• Like all members of the Felidae family, cats are specialized for a life of hunting other animals.
• 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.

There are also farm cats, which keep mice and rats away; and feral cats, which are domestic cats that live away from humans. Understanding cats’ place in history and human evolution reveals how very recently domestic cats came indoors and how millions of this species—who we call community cats—continue to live healthy lives outdoors today, as all domestic cats are biologically adapted to do. There are also domestic cats which live without being cared for by people. As domestic cats spread around the world along trade routes, the species became well adapted to life with humans.
