In 2013, Silvia Perego of Veselka Siberian Cattery in Italy described more such cats. Her stud
male, Yankee, came from Poland and is a black silver tabby with white. When he arrived at
her cattery at 4 months old, she noticed that he had a "strange" golden-brown spot on his neck

included a silver tabby daughter, Lady, who had the same golden-brown spot on her neck.
Another litter included a daughter, Lizzy, with the same spot
