Kittens should ideally be at least 12 weeks old before being given away or adopted. This age allows them to be well socialized, learn important life skills such as appropriate play, communication, litter box use, grooming, and hunting, and ensures they are fully weaned from their mother

. While some shelters and rescues allow adoption starting at 8 weeks, breeders often wait until 12 to 14 weeks to ensure kittens develop properly and have better long-term outcomes

. Kittens younger than 8 weeks are generally not recommended for adoption unless they are orphans or rejected by their mother and are adopted with siblings to maintain socialization

. In summary:

• Minimum age for adoption: 8 weeks (common in shelters)
• Recommended age for adoption: 12 weeks or older (preferred by breeders and experts)
• Extended stay (up to 14-16 weeks) is ideal for best social and behavioral development

This timing helps ensure the kitten is healthy, emotionally stable, and ready to thrive in a new home.
