Why are Tigers the biggest cats in world?

Tigers are not the biggest cats in the world. That title belongs to the Siberian tiger, which is the largest cat species by weight and size, but even then, there are other animals that could be considered larger:

* Polar bears are generally larger than Siberian tigers.

* Kodiak bears are even larger than polar bears.

However, if we're talking about the biggest cat species in the world, then the Siberian tiger takes the crown.

There are a few factors that contribute to the Siberian tiger's size:

* Genetics: Siberian tigers have specific genetic traits that make them larger than other tiger subspecies.

* Habitat: The Siberian tiger's habitat is cold and snowy, which requires them to have a larger body mass to stay warm and hunt successfully in harsh conditions.

* Diet: Their diet of large prey like deer and elk provides them with the nutrients and calories necessary to maintain their size.

It's important to note that while the Siberian tiger is the largest cat species by weight, other species like the African lion can be taller and longer than the Siberian tiger. However, the Siberian tiger is the largest feline in terms of overall size and weight.
