Sabertooth tigers are a type of carnivorous mammal that lived during the Pleistocene epoch. The sabertooth tiger is the largest known species of cat, reaching up to 9 feet in length and weighing up to 700 pounds. It was once thought that the sabertooth tiger was a subspecies of the tiger, but it is now believed that they were in fact a separate species.
