When is a Manx cat fully grown?

Most Manx cats reach their full adult size by 12 months, with some males continuing to add muscle mass until around 18 months. Their adult weight range is typically 3.6–5.4 kg (8–12 lb).

How fast should my Manx kitten grow?

Healthy kittens typically gain around 100 g per week during rapid growth phases. By 3 months, most Manx kittens weigh 1–1.5 kg; by 6 months, approximately 2–3 kg; by 12 months, close to adult weight.

When should I switch from kitten food to adult food?

The transition to adult food is generally appropriate around 9–12 months, when growth has largely completed. Switch gradually over 7–10 days by blending increasing amounts of adult food with the kitten formula.
