Pocket Leopards Bengals cattery is a long time bengal cat breeder in Northern California (Sacramento California). The owner, Terra Sinclair, has specialized in charcoal bengal cat genetics almost since the start in breeding bengal cats. 
Terra Sinclair has contributed her research and DNA samples in charcoal bengal cat genetic research to both UC Davis and Texas A&M. This research was a big contribution as it led to the confirmation and publication of the mode of inheritance of charcoal bengal coat pattern, and also lead to the development of a DNA test so that breeders world wide could test, and breed for this coat pattern.

Here is what UC Davis VGL website says regarding this: https://www.vgl.ucdavis.edu/services/coatcolorcat.php
​"Charcoal Pattern - Bengal Cat
​The Bengal cat breed consists of hybrid animals originally developed from crosses between the domestic cat (Felis sylvestris catus) and the Asian Leopard Cat (ALC) (Prionailurus bengalensis). Although the original intention was to replicate the exotic spotted ALC coat in domestic cats, some hybrids sport an unusual coat marking of a darker face mask and dark thick dorsal stripe (cape). This pattern has generated great interest among Bengal enthusiasts. Terra Sinclair, a Bengal Cat breeder, postulated from breeding outcomes that the “charcoal” pattern was produced by the combination of a domestic cat non-agouti allele (a) and an ALC agouti allele (APb), thus conferring the darker markings on their coat pattern. Research by Drs. Liza Gershony and Leslie Lyons has confirmed this mode of inheritance of the pattern. The VGL offers a test that helps breeders/owners determine the Charcoal status and breeding potential of their cats."

Although Pocket Leopards spearheaded the purposeful breeding of charcoal bengal cats, we still also breed for many other colors of bengal cats. We breed for brown bengals, silver bengals and snow bengals. 

We have a very small number of breeder cats at any given time, so that we can focus most of our energy on having healthy cats and proper socialization. We believe that a small program allows us to spend much more time socializing the kittens, and allows them more room to explore without having to be caged. We minimize the use of cages to only when absolutely necessary, which is not often. For more info about our cattery and how the cats are kept, please visit "our cattery" website page under the "About Pocket Leopards" menu link. 

Our goal is to contribute to the breed, not just breed cats. We also find great pleasure in making families happy with a healthy, social, long time companion.
