Acinonyx

This is a unique genus within the cat family, with only one living member, the cheetah.

Cheetah (Acinonyx jubatus)

Size: 20-70 kg | Status: Vulnerable

The fastest land mammal, the cheetah is the only cat without retractable claws — the grip helps it accelerate faster than any sports car (0-100 km/hr in 3 seconds). Cheetahs are not aggressive towards humans, and they have been tamed since the Sumerian era. They don’t breed well in captivity — picky females play hard to get. Cheetahs are not really big, and they hunt during the day to avoid competing with other big cats.
