So how do you know how big do cats get? While it’s hard to be completely certain, you can still come up with a decent approximation based on a wide range of variables, including genetics and habitat. Let’s discover more about feline development patterns and ways to assess how big do cats get!

5 Factors That Determine How Big Do Cats Get

1. Breed

One of the most significant factors in determining how big do cats get is their breed. Since they have an extended period for development before reaching maturity, bigger breeds require more time to accomplish growth. 

For instance, the largest breed of cats, the Maine Coon, might take up to 4 years to reach maturity. Even though the typical domestic cat weighs between 3 and 6 kilograms, grows about 18 inches long, and is around 25 cm tall when fully grown, cats may be smaller or larger than average depending on their breed.

2. Gender

Male and female cats have different growth patterns, as males cease maturing later in life and evolve more slowly than female cats. Furthermore, adult male cats frequently surpass or achieve greater ranges of length, height, and weight for their breed, which contributes to the fact that male cats are typically bigger than female cats. 

You may not have thought about it before, but now you know that how big do cats get is significantly affected by the cat’s gender.

3. Diet

Along with breed and gender, diet is another influential factor that impacts how big cats get. To grow to the right size, cats need to consume an excessive number of calories every day throughout their first few months of existence. 

In light of this, improper feeding of cats may interfere with their physical development, which explains why some shelter cats are smaller when compared to their adopted peers.

4. Intact

How big cats get is additionally determined by the age at which they are spayed or sterilized. Recent research suggests that cats who are spayed or neutered at an early stage can become larger than cats who wait until they’re fully grown. 

It’s essential to be aware that sterilizing a kitten too early could put them at risk for a bone injury known as a capital physeal fracture. This is frequently observed in bigger cat breeds or overweight male cats.

5. Genetics

While there is some natural variation in size among cats, feline dwarfism is frequently linked to a variety of health problems, including bone abnormalities brought on by nutritional imbalances and immune illnesses. 

Dwarfism is a rare genetic abnormality that results in asymmetric and undersized development in cats and therefore affects how big do cats get. Pituitary dwarfism, osteochondrodysplasia, and selective dwarfism are the three primary manifestations of dwarfism in cats.

When Do Cats Reach Their Full Size?

At first glance, the answer to the commonly raised question “How big do cats get?” could seem straightforward. However, to comprehensively understand the deeper aspects of this issue, we need to learn more about the cat’s growth characteristics.

Cats attain adolescence at the age of 18 months, which is equivalent to 21 years in human years. Cats have the potential to increase in size between 12 and 18 months, both in terms of height and weight.

You may predict your cat’s size by measuring it when it’s 16 weeks old and doubling that number. It’s not an exact measurement, but you can anticipate that the number will be close to your cat’s adult size.

Although cats have the opportunity to grow after their initial year, the pace of their development will dramatically slow down thereafter. If you measure your cat on an ongoing basis, you’ll be able to identify when the measurements start to stabilize since cats continue to grow taller and bigger every month.
