When do Manx cats stop growing?

Manx cats usually reach their full height by 12 months old, but these slow-to-mature kitties can continue to fill out and gain muscle mass until they are about three to four years old. Their final size depends on several factors, such as genetics, diet, and overall health. The size of the parents is a good clue about how big the kittens might get. A balanced diet with essential nutrients is crucial for their growth and development, and vet care and a healthy living environment also play a big role in their growth.

To help them reach their full adult size, Manx cats should transition to adult food around 12 months of age when they reach their full height. This transition is important because kittens require a diet specifically designed to support their developmental needs. Kitten food is formulated with higher levels of protein, fat, and other nutrients to help them develop strong muscles, bones, and a healthy immune system. Moving to adult food at the right time ensures they continue to get the appropriate nutrients as their growth rate slows down and their dietary needs change.
