Despite it's name, the sabre-toothed tiger was not actually related to the modern tigers that are found throughout the jungles of Asia. It is thought that the sabre-toothed tiger would have roamed across the grassland plains and open woodlands throughout both North and South America where individuals would of varied slightly depending on the area which they inhabited.
In the same way as modern day felines, the sabre-toothed tiger was a carnivorous animal and would of been the most dominant predator within its environment. Large herbivorous animals such as deer and bison would of been the most common prey of the sabre-toothed tiger along with occasional giant such as a small woolly mammoth should their ranges cross, although their exact diet is unknown.
The sabre-toothed cat would of been the most ferocious and therefore the apex predator within it's environment so had no natural predators on the American plains. Humans are thought to be the most likely cause for the demise of this enormous cat and more than 2,000 sabre-toothed tiger skeletons have been found emerged in the tar pits close to Los Angeles.
As with modern felines, the sabre-toothed tiger would of bred in the warmer months of early spring, when after a gestation period that could last as long as 8 months, the female sabre-toothed tiger would give birth to an average of 3 cubs per litter. Nothing is known about sabre-toothed tiger cubs but they could be born blind like the cubs of today's felines.
The sabre-toothed tiger is thought to have become extinct more than 12,000 years ago when human settlers first arrived in the Americas, hunting this species to extinction. Although climate change could also be the primary cause for their demise, little however is really known.
