I'll start with the smaller wild cats. All of these are no larger than a house cat. I have placed them with the smallest first, descending into the larger. I will eventually post all of the cat species on this thread-
don't post a cat thinking that I forgot it! I will eventually get to all of them!

Rusty Spotted Cat (
Prionailurus rubiginosus ) It's habitat is in India and Sri Lanka.

Black Footed cat. (
felis nigripes) It lives in southern Africa, and it does not have to drink water, instead, it gets all the moisture it needs from it's food. It is a very tenacious little cat and has been reported to attack sheep more than five times its own weight, hanging on to the neck until the jugular is severed. The natives even claim it can bring down a giraffe, although this has yet to be observed by scientists.

The Kodkod. (
Oncifelis guigna) It's habitat is Chile and Patagonia. The natives refer to it as the Guigna (Gween-ya), and it was once thought the cat was a vampire, because of marks it's canine teeth would leave on the necks of poultry.

The Oncilla (
Leopardus tigrinus)
Also known as the tigrina, little tiger cat, and little spotted cat. It lives in South America, and little is known about it.

The Flat-Headed Cat. (
Prionailurus planiceps) It is from southeast Asia, and is very unusual looking, with its long narrow head and flattened forehead. They eat fish and frogs, and are very happy to be near a river. They are not at all hesitant to submerge their entire heads in search of prey. They even have partial webbing in their paws. This cat is so rare that it was even declared extinct in 1985, and it still remains in danger.
