Animal Planet affectionately refers to Domestic shorthair cats as the mutts of the cat world because they're a mix of various breeds, resulting in a vast range of markings, colors, and personalities. With endless color and pattern combinations, they are a rainbow of cat cuddles.
Generally speaking, she falls into the medium category for height and weight, and much like her purebred, pedigreed relative, the American shorthair, the Domestic shorthair cat has a muscular build with a round face and eyes. Because she is of mixed ancestry, a Domestic may also be smaller or larger in stature, depending on her genetic makeup.
The World Cat Federation (WCF) notes that Domestics should have a balanced, solid body structure, with a head, nose, and ears that are proportionate to her body. But, as a trip to your local shelter will confirm, household cats come in many shapes and sizes.
