The Discovery of Shulamith
A black stray kitten with silky hair and uniquely curled-back ears wandered onto the doorstep of Joe and Grace Ruga. She became the matriarch of all authentic American Curls today.
🧬
A Harmless Genetic Feature
The curled ear is caused by a completely safe, autosomal dominant gene. It only affects the cartilage in the ears, which stays firm to the touch like a human's outer ear.

The American Curl is an elegant, medium-sized cat celebrated for its unique backwards-curving ears, sweet expression, and exceptionally loving personality.

They are not demanding, but they absolutely adore human companionship. Known for their gentle headbutting and soft chirrups, Curls integrate beautifully into active households and bond deeply with children, dogs, and other cats.

Care guide

What American Curl ownership requires

Curls are simple to care for, but their ears require gentle handling. You must never bend the firm cartilage of their ears backward or force them into different shapes as it can damage the canal.

👂
Ear Cleaning
Weekly check-ups are key. Clean with a soft, damp cloth if needed, and always handle the ear cartilage with extreme care without bending it.
🪮
Coat Grooming
Due to a minimal undercoat, a quick brush once or twice a week is all it takes to keep both short and longhair varieties looking pristine.
🧩
Cognitive Play
Highly intelligent and active. Provide plenty of puzzle toys, cat trees, and daily interactive games to satisfy their natural curiosity.

Health & lifespan

Known health considerations

The American Curl is a robust, healthy breed with a broad gene pool, resulting in zero breed-specific hereditary health issues. However, because their ears have firm cartilage, gentle handling is a must.

👂
Ear Canal Maintenance
Narrower ear canals in some individuals can trap wax. Regular check-ups prevent ear infections.
Low Risk
🧬
Cartilage Health
Avoid rough play or bending the ear cartilage. Keep children informed on how to pet their ears safely.

FAQ

Common questions about American Curls

Are American Curls born with curled ears?
No. All American Curl kittens are born with straight ears. The ears start to curl back between 2 to 10 days of age. They continuously unfurl and curl until they reach their permanent shape at around 4 months.
Are their ears fragile or stiff?
The lower portion of the ear consists of firm cartilage, similar to a human's ear, which should feel firm to the touch. The tips remain soft and flexible. While sturdy, they must be handled with gentle care to avoid breaking the cartilage.
Do they make a lot of noise?
No, they are generally quiet cats. When they want to communicate, they speak in soft, melodious trills and chirping sounds rather than loud meows.
