Do Kittens Have Baby Teeth They Lose?

Yes kittens have baby teeth that will be replaced by adult teeth.  If you look at a newborn kitten they will not have teeth.  Deciduous (baby teeth) erupt between 2-3 weeks of age and continue through 6 weeks.  Adult tooth eruption begins at 3 months (12 weeks) of age ends with the adult canines erupting at about 6 months of age.
Most owners rarely noted the loss of baby teeth; these are often ingested by cats and dogs.

Kittens will start to lose their baby teeth when the permanent teeth begin to erupt, usually beginning around 3 to 4 months of age. By 7 months of age the cat's adult teeth are fully developed.
