Book excerpt: Thanks to their fluffy, curled-back ears, American Curls are one of the most without difficulty identifiable cat breeds today. Although their coats can come in a extensive range of colours and patterns, the special ears of American Curls make them stand out amongst different cat breeds. Today, their backwards-curled ears are a proper trait amongst breeders, however they had been initially the product of a herbal (and harmless) genetic mutation. Despite their incredibly low weight--particularly in females--American Curls are muscular and have medium-sized bones, so they're no longer as refined as their physique weight and size may also at first imply. Their wedge-shaped heads, walnut-shaped eyes, and curled ears provide them a definitely special appearance.
