The American Shorthair is a popular cat breed that consistently ranks at the top of popularity charts.

They have a very cheerful and playful personality. Sometimes they can be a bit too mischievous, which might trouble their owners... Since they are athletic and active cats, it is a good idea to have cat furniture like a cat tree.

Also, you might be curious about how large they grow. In this article, we will focus on the "size" of the American Shorthair, including their weight, body length, and growth process.

Size of the American Shorthair

When you think of the American Shorthair, their round, adorable faces and distinctive swirl patterns are their charm points. When you touch them, you’ll find they are quite muscular and sturdy.

Are they larger than the average cat? Or are they smaller?

Powerful and sturdy build

The body type of the American Shorthair is classified as "semi-cobby." They have a well-balanced and powerful appearance with well-developed shoulders and legs.

Scottish Folds and British Shorthairs also share this semi-cobby type.

By the way, Persians and the Exotic Shorthair (featured in "An Old Man and His Cat") are classified as "cobby." They also have a sturdy build like the semi-cobby, but these cats have a rounder, stockier appearance.

Average Weight of the American Shorthair

The average weight of an adult American Shorthair is 3–5 kg for females and 4–6 kg for males. Since the average weight of a typical cat is about 3–5 kg, they can be considered a cat of average size.

Body Length of the American Shorthair

The body length (from chest to rump) of an American Shorthair is about 30–40 cm for both females and males. There is almost no difference in body size between males and females. Although they may look large, they are about the same size as the average cat.

Growth Process of the American Shorthair

While American Shorthairs are average in size, they are characterized by their muscular and sturdy build. Do they have a solid build even as kittens?

We have summarized the growth process of the American Shorthair below.

Weight Progression of the American Shorthair

Like other cats, the American Shorthair reaches adulthood around 1 year of age.

Because they are very active and get plenty of exercise, they develop a solid build by about 3 months of age. Their average weight at this time is about 1–1.5 kg.

They reach about 2–3 kg by 6 months and about 3–4 kg by 9 months. Growth stops around 1 year of age, when they typically weigh 4–6 kg.

American Shorthairs are Prone to Weight Gain

Originally, the American Shorthair lived as a "working cat," hunting mice and snakes. Their sturdy shoulders, chest, and lower body were developed through hunting.

With such roots, American Shorthairs are highly active. They also have a hearty appetite. They have a tendency to be "prone to obesity." Some can even become obese cats weighing over 8 kg...

Obesity can lead to diabetes and joint problems, so caution is required.

Obesity Prevention for the American Shorthair

If you live with an American Shorthair, "diet management" and "proper exercise" are essential.

For cats, gaining 15–20% or more over their weight at 1 year old is considered "obesity." It is necessary to weigh them regularly, check their obesity level using a BCS (Body Conditioning Score), and switch to diet food as appropriate.

Ensure the daily food intake does not exceed the recommended amount, and be careful not to give too many treats. You must never feed them human food.

Additionally, you need to create an environment where they can exercise indoors. Prevent inactivity by playing with toys with them and installing furniture like cat trees or cat walks.

Summary

Affectionately known as "Amerishor," the American Shorthair is a cat breed with a charming, cheerful, active personality and adorable expressions.

While they are sturdy and muscular, they are not particularly large cats. They are about the same size as the average cat, with an average adult weight of 3–6 kg.

While they are active and playful, they are also prone to obesity. You must maintain their health by ensuring "diet management" and "proper exercise."

Although American Shorthairs are famous for "disliking being held," they love playing with their owners. They put their all into playing with teaser toys and hunting games. Enjoy playing with them and have fun managing their weight.
