What is the most common domestic cat?

It's difficult to definitively say which breed is the most common domestic cat worldwide, as registration data varies across countries and organizations. However, the American Shorthair is often considered the most popular breed in the United States, and is likely a strong contender for the most common breed globally.

Here's why:

* Popularity in the US: The American Shorthair is the most popular breed in the United States according to the Cat Fanciers' Association (CFA).

* Wide Distribution: American Shorthairs are found all over the world, thanks to their history as working cats on ships.

* High Number of Unregistered Cats: Many cats, particularly those from mixed backgrounds, are not registered with any breed organization. This makes it difficult to track their numbers accurately.

Therefore, while the American Shorthair is a strong contender for the most common breed, it's important to remember that there is no definitive answer due to the vast number of unregistered cats worldwide.
