Kittens develop at different rates. Use this overview to guide your observations, not as a rigid timetable.
0–2 weeks: rest, milk and weight
Newborn kittens depend entirely on their mother. Monitor daily weight gain, suckling, warmth and cleanliness. Contact your vet if a kitten is not thriving or gaining weight.
2–4 weeks: senses and movement
Eyes and ears develop and kittens gradually become more mobile. Provide a safe environment and let the mother cat set the pace of contact.
4–8 weeks: play and first experiences
Play, interaction with littermates and positive contact with people become important. Gradually introduce suitable food, a litter tray and everyday household sounds without overwhelming the kittens.
8–12 weeks: social learning
Continue brief, positive experiences with handling, coat care, the carrier and normal household noises. Follow your vet’s vaccination and health-check schedule.
12–14 weeks and moving home
Under FIFe breeding rules, kittens must generally not leave before 14 weeks, and current requirements for vaccination, identification and documentation must be met. Always check the latest rules. Give buyers written information about feeding, health, care and settling into the new home.
