Even if a cat has always been more adult and seems to grow at lightning speed from the age of eight weeks, it is still far from fully grown. It takes the young animal around twelve months, or one year, to reach its final size - however, as always, exceptions confirm the rule.

Differences in the cat breeds

When the cat is fully grown also depends on its breed. There are early developers like the Siamese cat and late developers like the gigantic Maine Coon cat. The latter takes about three years to reach its final height and weight. Depending on the breed and gender, the development of hangover cheeks can give the impression that the animal is still growing, because the strong animal makes the whole animal appear more massive. It is also possible that the cat will still put on fur properly after growth has been completed and thus appear larger.

Change through posture and living conditions

Even if you can assume that most cats are fully grown by the year, you may still notice changes in your house tiger. These mainly affect the stature of the cat, but can give the impression that it is still growing. A possibly still not castrated one year old can be significantly lankier and therefore also appear smaller than a somewhat older, castrated male who has acquired a more comfortable stature.

An active, sporty freelancer can still put on a lot of muscle and thus appear bigger and stronger, although the shoulder height has remained. If certain factors disrupt growth, such as malnutrition or illness, growth can take longer or even be interrupted.
