Each type of companion animal has its own unique type of teeth, depending on what type of food the animal normally eats. For example, a meat-eating animal such as a cat has quite different teeth compared to a grass-eating animal such as a horse. However, all domestic animals have 2 sets of teeth during their lives, as humans do: a set of deciduous (“baby”) teeth that fall out, and a set of permanent teeth that come in later.

Most cats have 26 deciduous teeth and 30 permanent teeth. The deciduous incisors begin to erupt at 2 to 4 weeks of age, and the deciduous premolars at 5 to 6 weeks of age. Permanent teeth usually begin to appear at around 4 to 7 months (See table: Feline Adult Dentition).
