Maine Coon Bristow. Without the white Bristow would be a black tortoiseshell. But with the white he is a dark colored calico to me. Amazing and arresting appearance. The orange section of his fur is diluted.
Update: Bristow’s history — He was Best Maine Coon Great Lakes Region, 11th Best Longhair Cat Great Lakes Region, Tied for 19th Best All Breed Cat Great Lakes Region, Smoke Tortie and White, Owners: by Laura and Joe Kembitzky
