Bred from a cross.
The Bengal is a young breed. It arose from the 1960s onward in the United States, crossing the Asian leopard cat Prionailurus bengalensis with domestic cats — with the stated aim of an animal that looks like a wild cat and lives like a domestic one.
What comes from the wild form is essentially the coat. Everything else — size, temperament, needs — comes from the many generations of domestic cat in between. How many that is, and where the law draws its line, is set out just below.
