This seems to be a fairly new development to extend the range of coat types for this popular wildcat hybrid. They are a monochromatic Bengal. There are 50 shades of grey, the breeders say. They appear to be quite rare and they come in a spectrum of slight variations from charcoal in silver, snow, brown et cetera. They have a dark, thick dorsal stripe called a “cape”. They say that the charcoal pattern is produced by the combination of a domestic cat non-agouti variant and Asian Leopard cat agouti variant (UC Davis Veterinary Medicine Veterinary Genetics Laboratory).

The pattern is unusual with a darker face. The markings are darker and more extended than is typically seen on the Bengal cat. The mode of inheritance is not fully understood. The experts say that the APb variant appears to not be fully dominant over the a variant.
