You can't really train a leopard, I don't think. The chances are the leopard would just eat the policeman. Dogs are much more effective for that sort of... And you can't have drugs cats either. But cats weirdly do have a herb that seems to make them high. Have you seen that? Yeah, catnip. Catnip is a sort of herb that grows naturally and cats love it and it makes them go all high. It's hilarious. They sniff it and they start rolling around on the ground and they drool everywhere. There was a big part of hunting and every nobleman and probably, though down, people had hunting dogs in medieval times
