The Lykoi is a cat breed developed from a naturally occurring coat mutation in domestic cats, first identified in the United States. It is known for its partially hairless, roan coat and facial “mask,” which give it a wolf-like appearance. The breed name comes from the Greek word for wolves.

Origin and development

The Lykoi breed was developed from naturally occurring mutations found in feral or domestic short-haired cats in the United States. Breed accounts describe it as a recent addition to cat fancy, with formal recognition following its discovery.

Physical characteristics

Lykoi cats are medium-sized and have a distinctive coat pattern that may appear patchy or partially hairless. Breed descriptions note a lack of undercoat, sparse hair on the ears, face, legs, and feet, and a roan coat pattern.

Breed recognition

The breed has been recognized by The International Cat Association. The Governing Council of the Cat Fancy granted the breed first-stage recognition in 2017 and preliminary recognition in 2020.

Temperament and care

Breed guides commonly describe the Lykoi as active and people-oriented, though individual temperament varies. Care discussions often focus on the needs created by the breed’s sparse coat and skin exposure.
