Flat-headed cats are endangered because of pollution and because humans catch too many fish but mostly because humans have cut down the forests to build farms. Flat-headed cats like forests that are not too far above sea level, and this makes good farmland, so humans want it. Some scientists think that flat-headed cats can live in forests that have grown back after being cut down. Scientists do not think the flat-headed cat can hunt and live near farms the way the Iriomote cat does.
