The Chinchilla look is a silver coat on a Persian-type cat. Each long white hair is tipped with black, which gives the fur its shimmer, and green or blue-green eyes with dark rims finish the picture. The line traces back to Silver Lambkin, an English cat born in 1882. Most registries treat chinchilla as a Persian color rather than a separate breed, and cats listed as Chinchillas are often Persians or Persian mixes.
In Seattle, a Chinchilla is an indoor cat. Coyotes are common in the city's larger green spaces, and a slow-moving, flat-faced cat is safer inside. Expect a calm, quiet companion that likes a predictable day, plus daily combing, regular baths and face cleaning. Cats vary, so how a particular cat handles touch and noise matters more than the label.
