Not everything that looks like a cat is a cat

The Thylacosmilus looks very like a sabre-tooth cat. It has a cat-shaped body and long stabbing teeth to kill prey. However, it is a marsupial hunter which is more closely related to the kangaroo than it is to cats.  Thylacosmilus lived in South America about 4 million years ago.
