Here's a timeline:
* 3-4 weeks: Kittens start to show interest in solid food and may nibble on their mother's food.
* 4-6 weeks: Kittens begin to eat solid food regularly and may start to eat more than they nurse.
* 6-8 weeks: Kittens are typically weaned completely and can eat solid food on their own.
Important Note: This is a general timeframe and can vary depending on the individual cat and kittens. Some kittens may wean earlier or later than others. It's important to monitor the kittens' development and make sure they are getting enough to eat.
If you are concerned about your cat's kittens, it is always best to consult with a veterinarian.
