Iriomote cat
The Iriomote cat has six pairs of incisors, two pairs of canine teeth, four pairs of premolars, and two pairs of molars for a total of 28 teeth. Compared to other cats, including small wild cats, the Iriomote cat is lacking one pair of premolars on the top jaw behind the canines. In addition to this, unlike most other subtropical mammals, Iriomote cats' teeth give details about their year-to-year history. It is expected that these details will help determine the age and behavior of the cats.
