In cats, the process of tooth eruption typically occurs in a predictable sequence. Kittens are born without teeth, and their first set of teeth, known as deciduous teeth or baby teeth, begins to erupt at around 2 to 3 weeks of age. These baby teeth will eventually be replaced by adult teeth.

Eruption Timeline: Transitioning from Kitten Teeth to Adult Teeth

Adult teeth begin to erupt as the kitten ages, usually starting around 3 to 4 months of age.

Incisors: These are the small teeth found in the front of the mouth. These teeth erupt at 3-4 months of age.
Canines: These teeth are the long, pointed teeth behind the incisor. These teeth erupt at 4-5 months of age.
Premolars: These teeth are the sharp-edged teeth located behind the canine teeth. These teeth erupt at 4-6 months of age.
Molars: These teeth are located in the back of the mouth behind the premolars. These teeth erupt between 4-5 months of age.

By the time a cat reaches about 6 months of age, it should have most, if not all, of its adult teeth, totaling 30 teeth (12 incisors, 4 canines, 10 premolars, and 4 molars).
