“I meant," said Ipslore bitterly, "what is there in this world that truly makes living worthwhile?"
Death thought about it.
CATS, he said eventually. CATS ARE NICE.”

― Terry Pratchett, Sourcery

Even on a disc world carried on the backs of elephants that are in turn riding a giant spacefaring turtle, it is a truth universally known that cats are indeed very good. 

This badge features the Death of Discworld fame dressed in his trademark black hood, above a banner that reads in all caps, "CATS ARE NICE". The badge measures 38mm in diamter and fastens with a sturdy safety style pin.
