Just a note there are no such breed as snow tigers. There are white tigers who are a genetic mistake that would not survive in the wild. The only reason they exist is that man keeps breeding them to use as Zoo attraction as normal humans thinking about themselves before the animals
Most of the white tigers can be traced back to a pair caught in the 1950's in india. If you look at the coloring of a white tiger its not equiped to survive in normal tiger habitat as there obviously not camoflaged. As much as they look gorgeous ther existance still makes me angry. We have a big cat sanctuary near us and they neuter all white tigers they get as they will be no part of the continued inbreeding of a genetic mistake. There is a good site here that gives the history of the white tiger
Sorry bout the preaching but it makes me angry.
Any way back to the subject my favourite wild cat is the snow leopard have a look at the conservation site
