A Chinchilla is usually a Persian with silver tipping: each long white hair ends in a dark tip, which gives the coat a frosted shimmer. The look traces to an English cat named Silver Lambkin, 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. Green or blue-green eyes with dark rims are typical.
In a Philly home, the personality is the easy part. Chinchillas tend to be calm, gentle and quiet, and many prefer routine to roughhousing. The coat is the work. Plan on combing every day, regular baths and wiping the face, since long hair mats and flat faces collect tear stains. Cats vary, so a Chinchilla may be livelier or shyer than the typical description.
