Updated: October 2026
Overview
The American Curl is a medium-sized cat famous for its uniquely backward-curling ears. Unlike the Scottish Fold mutation, the American Curl gene affects only cartilage in the ears with no associated skeletal or systemic disease - making the breed a welfare-friendly alternative for owners who want unusual ears.
History & Origins
In 1981 a stray longhaired black cat with curled-back ears appeared at the home of Joe and Grace Ruga in Lakewood, California. The cat (Shulamith) became the foundation of the breed. Her kittens were curl-eared too, identifying a dominant gene. TICA gave the longhaired American Curl championship status in 1992, and the CFA later admitted the breed to its championship class with both longhair and shorthair divisions.
Kittens are born with straight ears; the curl develops over 3-7 days, then settles into a permanent shape by 4 months.
Appearance
Medium-sized, balanced. Adults weigh 3-5 kg (7-11 lb).
- Coat: two varieties: shorthair (silky, close) and longhair (silky, semi-long with feathered tail).
- Colour: all colours and patterns.
- Ears: curled backward 90-180 degrees in a smooth arc. The cartilage feels firm but flexible.
- Eyes: walnut-shaped, expressive.
- Body: semi-foreign: moderate, balanced.
Temperament & Character
Friendly, playful, intelligent. The breed bonds strongly with family, is excellent with children, and remains kitten-like into old age. Many Curls are described as "Peter Pan cats" for their lasting playfulness.
Care
Coat & Grooming
Shorthair: weekly brushing. Longhair: 2-3 times weekly.
Clean ears weekly - the curl traps wax and debris. Gentle handling: the cartilage is firm but can be damaged by rough manipulation.
Trim claws every 2 weeks. Brush teeth several times weekly.
Health & Lifespan
12-16 years.
- Hypertrophic cardiomyopathy (uncommon).
- Ear infections - curled shape can trap debris.
The breed is generally healthy. No major breed-specific genetic diseases - unlike the Scottish Fold mutation, the American Curl gene affects only ear cartilage.
Pros & Cons
Pros: unique appearance, healthy, family-friendly, long-lasting playfulness. Cons: ears need regular cleaning; cartilage can be damaged by rough handling.
