Saber-toothed squirrels (also known as vampire squirrels due to their large saber teeth) are a former extinct species of squirrel native to Eurasia and North America. They resemble a cross between a squirrel and a feral cat, but has large saber-like teeth, but these teeth are not designed to hunt smaller animals, instead they use these teeth to fight with other saber-toothed squirrels in their territory or to win a mate. Like today's squirrels, they mainly feed on grass, roots, tubers, seeds, nuts, and fruits. It is unknown why they became extinct in the Late Pleistocene, some people once thought they were outcompeted to extinction by modern-styled squirrels (including red squirrels, gray squirrels, etc.), but people had brought them back from extinction through time travel and discovered that the modern-styled squirrels had no impact to the saber-toothed squirrels, so scientists and palaeotologists had proven that the climate change was the cause of the saber-toothed squirrel's former extinction, but one thing is for sure that they did not cause any changes to earth's environments nor causing extinctions that movies had shown.
