Bengal cat
Found: Originally bred in North America in the 1960s
If you thought all felines were creeping cowards, take a look at this macho moggy. The Bengal is a domestic cat/leopard hybrid and like all good crossbreeds, they're completely crackers.
You won't find a Bengal down at your local RSPCA however as they cost an absolute fortune. It'd be worth every penny though, just to see your neighbour's pitbull cower at the sight of your little puss.
