When does a Japanese Bobtail stop growing?

A Japanese Bobtail cat typically stops growing in height by around 12 months of age. However, they will slowly continue to fill out and reach their full size, including muscle development and overall body mass, until they are about three years old.

Several factors influence the growth rate and final size of a Japanese Bobtail, including genetics, diet, health, and overall care. Proper nutrition is crucial during their growing phase to ensure they develop strong bones and muscles. High-quality kitten food, which is rich in protein and essential nutrients, supports their growth and energy needs.

You should consider switching your Japanese Bobtail to adult cat food when they are about 12 months old, as this is when they typically reach their full height and their growth rate begins to slow down. Consulting with your vet can provide personalized guidance on the best time to make this transition based on your cat’s specific growth and health needs.
