Just cause you're a big cat, doesn't mean you're a Big Cat.

The definition of "Big Cat" has varied from media to media. In some content, reporters call cougars, bobcats, and some members of the smaller cats (Felidae) big cats, but there is an important distinction between them. Scientifically big cats of the genus Panthera have the ability to roar, thanks to their special hyoid structure. Small cats, wild and domestic, can purr but cannot roar.

Licensed zoos, sanctuaries, and academic institutions with big cats may continue to operate. Facilities may still exhibit their animals but cannot offer the public hands-on experiences. Private owners of big cats may also keep their animals, but no further breeding will be allowed, and they cannot obtain more cats. Owners must notify the U.S. Fish and Wildlife Service about their animals within 180 days of the law’s passage.
