By weight:
* Siberian Tiger: The Siberian tiger is the largest cat species by weight, with males reaching up to 700 pounds.
By length:
* Siberian Tiger: The Siberian tiger is also the longest cat species, with males reaching up to 11 feet in length.
By height:
* Lion: While the Siberian tiger is the longest and heaviest, the lion is considered the tallest cat species, with males reaching heights of up to 4 feet at the shoulder.
Other contenders:
* Amur Leopard: The Amur leopard is the rarest cat species and has been considered to be the largest cat in the past. However, its size is comparable to the Siberian tiger.
Ultimately, the "biggest wild cat" depends on how you define "biggest." The Siberian tiger is the clear winner when considering both weight and length. However, if height is the deciding factor, the lion takes the crown.
