Only seven living large cats remain from an important and remarkably diverse radiation of felid carnivores that began in the mid-Tertiary period approximately 25 million years ago. Fortunately, these surviving members of the feline family are quite easily distinguished morphologically, differing significantly in body size and have some distinctive features of predatory behavior and killing practices, as well as display differences in territorial and social behavior. . Big cats are admired and most often visited in zoological gardens. They also receive a lot of attention when observing animals in their natural habitat. However, all of them have significantly reduced their geographical distribution over the course of human existence, experiencing significant declines in numbers this century.
