The Wirehair is a medium-to-large cat. Its body is slightly longer than it is tall and is well-muscled and powerful, showing good depth of chest. As in most breeds, the females are usually smaller than the males, but they do not appear frail or dainty and should not be penalized because of any actual or perceived size difference. The American Wirehair’s head is broad, with a prominent chin and well-developed cheekbones set on a well-muscled neck. In profile, their nose shows a gentle indentation. Their ears are medium in size, widely set and slightly rounded at the tips. Their eyes are large, round and piercing. The Wirehair’s feet are rounded, compact and tight. The tail is in proportion to the body, tapering gently from rump to end and being neither blunt nor pointed.

The American Wirehair is characteristically a people-oriented cat, with a strong, affectionate personality and a keen interest in its surroundings. The Wirehair is always looking for a way to amuse himself, and his owner. They have been described as quiet, reserved and loving, although to their owners these cats are personable and active.
