The Laughing Cats

Catwoman seems to be the suspect in the theft of a rare Black Siberian Leopard, but it soon turns out that Joker is behind the theft when Batman and Batgirl investigate and attempt to protect a second leopard of the same breed, unaware that Catwoman is interested in the matter. When all three discover that the cats were stolen for Killgore Steed, the owner of several dangerous creatures, no one anticipates Joker double-crossing him and using his personal maze and creatures to put an end to Batman, Batgirl and Catwoman.
