An adult cat with all its teeth will have 30 teeth, 16 in its upper jaw and 14 in its lower jaw. Many cats have teeth extracted, however, due to tooth decay, and many will lose teeth for other reasons.

Feline kittens have 26 deciduous teeth, and adult cats have 30 permanent teeth - 12 incisors, 10 premolars, 4 canines, and 4 molars. Most of the teeth in a cat are very small and you can only see them if you look very close. Kittens have baby teeth, which usually appear at 2 to 3 weeks of age and are replaced by permanent teeth around the age of 7 months.
Including wisdom teeth, adult humans should have 32 teeth.
