A kitten's teething period typically occurs 2-3 weeks after birth, as this is when they begin to grow their baby teeth. The baby incisors are usually replaced by the permanent incisors between 4 and 6 months of age, and then by the permanent canines around 5 months. This process usually continues until the kitten is about 8 months old.

Actually, during teething, cats may experience a decreased appetite, will seek out things to chew on, and may even experience swollen and bleeding gums, as well as frequent drooling. At this time, pet owners should provide easily chewable food, such as softened cat food or canned food, to help them comfortably get through this period.
