Kittens can typically leave their mother when they are fully weaned and socialized, which usually occurs between 8 to 12 weeks of age. During this period, kittens transition from nursing to eating solid food, learn essential survival and social skills from their mother, and develop emotional stability. Separating kittens too early (before 8 weeks) can cause health problems, behavioral issues such as anxiety or aggression, and difficulties in socialization. Many experts recommend a slightly longer period, up to 12 to 16 weeks , to ensure kittens receive full socialization and behavioral guidance from their mother and littermates. This extended time helps kittens learn how to interact with other cats and humans and supports their emotional and physical development. Key signs that a kitten is ready to leave its mother include:

• Eating solid food independently
• Consistent use of the litter tray
• Healthy and steady growth
• Comfortable social interaction with humans and other animals
• Ability to play independently without relying on the mother

In summary, while the minimum age is around 8 weeks, it is ideally better for kittens to stay with their mother until 12 weeks or more to avoid potential health and behavioral problems and to support their overall well-being.
