The tiger, lion, jaguar and leopard are classically known as Big Cats and are the only cats able to roar. A more expansive definition of the term also includes the cheetah, snow leopard, clouded leopard and cougar.
They typically have strong sharp claws and well developed prominent canine teeth. All cats are carnivores, surviving on diets consisting mainly or exclusively of meat. Big Cats are apex predators, meaning they hunt other animals and have no predators of their own.
Apex predators play a crucial role in maintaining ecosystem balance. Chester Zoo is home to four magnificent species of Big Cats.
