White tigers are hunted by poachers and used for Chinese medicine. The white tiger is not a species unto itself so cannot be classed as endangered. It is a genetic flaw of the Bengal tiger, and extremely rare. This Is Not A Tiger, ; It's a Leopard !
Cheetah is very popular in culture right know and I can't help but love it too, I have tons of cheetah stuff. The animal is very fierce and I think that is why it is so popular, it represents a fierce or wild side of people.
