Domestic Shorthair

Domestic Shorthair is a term for a cat with short hair and mixed or unknown ancestry, rather than a formally recognized cat breed.

Domestic Shorthair is a term for a cat with short hair and mixed or unknown ancestry, rather than a formally recognized cat breed. It is commonly used for ordinary household cats and shelter cats with varied appearances and temperaments. The term is especially common in North America and is comparable to “moggie” or “house cat” in other English-speaking regions.

Definition

Domestic Shorthair refers to a cat with short fur and no known or standardized pedigree. It is used as a broad category for mixed-ancestry cats rather than a breed with fixed traits.

Appearance and traits

Domestic Shorthairs can come in nearly any coat colour or pattern, and they vary widely in size, build, and temperament. Because they are not bred to a standard, individuals may resemble many different breeds without actually belonging to them.

Usage of the term

The label is commonly used by shelters, veterinarians, and pet owners to describe short-haired cats of mixed or uncertain background. It is often used interchangeably with informal terms such as house cat or moggie.

History and background

Domestic Shorthairs descend from long histories of free-breeding domestic cats rather than from a single planned breeding program. Sources commonly connect modern domestic cats to ancient domestic cats in the Middle East and Egypt.
