A domestic short-haired cat is a cat of mixed ancestry—thus not belonging to any particular recognized cat breed—possessing a coat of short fur. In British English, they are often referred to as moggies. Domestic short-haired cats should not be confused with the British Shorthair, American Shorthair, or other standardized breeds with “Shorthair” names, which are breeds recognized by various registries.
Domestic short-hairs are the most common cat in the United States, accounting for around 90–95% of their number.
Other generic terms include house cat and alley cat. The term tabby cat technically refers to a coat pattern but is also often used as a general term for cats of this sort.
Domestic short-haired cats are characterized by a wide range of coloring, and typically “revert to type” after a few generations, which means they express their coats as a tabby cat. This can be any color or combination of colors. They also exhibit a wide range of physical characteristics, and as a result, domestic short-haired cats in different countries tend to look different in body shape and size, as they are working from differing gene pools.
