Tiger
The tiger ("Panthera tigris") is the largest species among the Felidae and classified in the genus "Panthera". It is most recognisable for its dark vertical stripes on reddish-orange fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about
Big cat
The term "Big cat" is typically used to refer to any of the five living members of the genus "Panthera", namely tiger, lion, jaguar, leopard, and snow leopard.
Except the snow leopard, these species are able to roar.
A more liberal and expansive definition of the term includes species outside of "Panthera" including the cougar, clouded leopard, Sunda clouded leopard, cheetah and sometimes the several lynx species, although these added species also do not roar.
