Concerning Cat mouths

Now we will look at a carnivore’s mouth, the cat mouth.  Cats are “diphyodont”, which means they have two sets of teeth, the deciduous teeth shed and are replaced by the second, permanent set. Kittens are born with no teeth. At about 3 to 4 weeks of age, the deciduous teeth begin to erupt. By 6 weeks of age, all 26 deciduous teeth are present. At 4 to 5 months of age, the deciduous teeth are lost and the permanent teeth erupt. By six months, all of the adult teeth will have erupted.  Adult cats have four types of teeth. The incisors, canines, premolars, and molars. In the upper jaw (the maxilla), there are 6 little incisors, two canines, three premolars, and one molar. The incisors are used mainly for picking up objects and for grooming. The canines are used for holding prey, and for slashing and tearing when fighting. Premolars function mainly for breaking food into small pieces, as well as for carrying and holding. The molars have flat surfaces and are used to grind food into small pieces. In the lower jaw (the mandible) you’ll find the same number of incisors, canines and molars, however, there are only two premolars instead of three. The total number of permanent teeth in a cat is 30. Ultimately, cat’s mouths are perfect for the carnivorous little felines.
