2. Iriomote cat
Being approximately the same size as your regular domestic cat Iriomote cats are found on one island in Japan. In 1994 there were only 100 known kitties left of this kind. Scientist believe that over the years their numbers only diminished. The biggest threat to their existence is the fact that Iriomote cats breed with domestic cats which in return compromises the ability to maintain their genetic identity for future generations.
