The American Curl is a highly distinctive cat with elegant, wispy ears that curl backwards in a graceful arc, creating an alert, sophisticated look similar to that of a wild lynx. Kittens of this breed are born with straight ears. Within 4 or 5 days, however, their ears begin to curl back in a tight rosebud formation. Gradually, they unfurl, reaching their permanent shape by about 16 weeks of age. The degree of ear curl varies widely within the breed. Fanciers prefer a more dramatic curl for the show ring, while straighter-eared specimens are typically considered to be pet-quality. Some kittens in American Curl litters never develop the curly-eared trait. This breed is small to medium-sized, comes in a variety of colors and may be either long or short-haired. Either way, its coat is silky and lies flat, with little-to-no undercoat, so they are not prone to a great deal of shedding. The tail of the American Curl is fluffy and fan-like, said to resemble a feather boa. It should be brushed regularly.

In addition to its unique ears, the American Curl has an extraordinary disposition. People-oriented, playful, faithful and highly affectionate, these cats remain kitten-like well into adulthood, and usually throughout their lives. They are remarkably adaptable to new situations and are not easily stressed. American Curls adjust to almost any type of household, are gentle with children and get along extremely well with most other cats and with dogs. They are rarely territorial and typically can be introduced into a home with established pets with relative ease, as they tend to be very respectful of other animals. American Curls form very close bonds with their primary caretakers. Owners can expect their Curls to follow them from room to room throughout the house – and sometimes, even into the shower. They demand plenty of personal cuddle-time and one-on-one attention. This is an easy-going breed that is eager to please.
