When Do Cats Stop Growing? Here’s When Cats Reach Their Full Size

Your furball is too small to play with? Are you not noticing her collar size-changing anymore? Are you interested to know when your finicky furball will grow to her full size? Here is what you should know.


Let me tell you about a typical growth cycle of a cat. These are the life stages of a cat, regardless of her breed.

Kitten: 0 – 6 Months old

From day one of their birth to the sixth month is when you will see fast-paced growth. Kittens in this early stage grow rapidly.

Junior: 6 months – 2 years old

Cats grow during this stage too, but it is comparatively slow. They need to be nurtured and given quality playtime.

Prime Adult: 3 – 6 years old

Cats are settled in this period. They are no longer in the growth phase and lead a healthy prime time.

Mature Adult: 7 – 10 years old

In this stage, they are more prone to obesity and other health issues, much like an aging human.

Senior: 11 – 14 years old

Most often, cats are in their final stages of life when they reach 11 years and above. Depending on their breed, health, and parenting, their lifespan may vary.

What is the maximum size of my cat? When exactly will my cat stop growing?
This is a subjective answer that is dependent on various factors like your cat’s breed, her lifestyle, food habits, environment, and so on. But according to vets and experts, the maximum size/weight of a cat is double its weight, like a kitten in four months. There is also another expert opinion that says that on average a domestic cat is around 10 pounds in weight.
Irrespective of the breed, most cats stop growing after 1 year of age. This is a common observation and may not be the exact case for your specific feline age and breed.

In all, do not worry about her size, unless she becomes a big round heavy fur ball that is obese, you need not really be concerned about her size. Typically, every breed has its own way of growth traits. While there are also dwarf cats, you cannot really compare between one another to make sure that your cat is now fully grown.
Kudos… and happy cattying…
