A coat pattern in cats controlled by the sepia alleles (cb/cb). e.g. Burmese. A cat with these alleles has slightly thermo-liable tyrosinase and thus results in a coat pattern that has normal pigmentation on the tail, legs, face and ears, and slightly lighter coat pigmentation on the body. The sepia alleles (cb/cb) are the least thermo-liable tyrosinase of cats from the Himalayan series. See Himalayan Series.
