Batman #323 (1980)

Batman attempts to arrest Selina Kyle on suspicion of robbing Riverside Museum's Egyptian urns, as the guard has been assaulted by a cat-clawed crook. But Selina knows she might die in prison from her disease, and, tossing her pet cat at Batman, uses the diversion to escape. The next morning, when Bruce Wayne steps into his office and meets his new secretary Caroline Crown, he is met by Catwoman, who asks his aid and denies that she pulled the museum robbery. Bruce asks her to turn herself in, but Catwoman can't allow that to happens and she sprays Bruce with catnip treated to produce a sneezing fit, and Bruce finds her gone when he recovers. In the meantime, Lucius Fox is concerned for the finances of Wayne Enterprises, which adds more to the stress of dealing with his young son, Tim, who is apparently running with the wrong crowd. That night, Batman goes to the scene of the robbery and recovers a thread from the display case of the urns. The dust on the thread leads Batman to the Ajax Import and Export Warehouse, which locale Catwoman has already pried from a thug. The two meet and clash, but Catwoman accidentally trips off a poison-gas booby trap. Batman, donning a gas mask, takes them both to safety and they agree to stop fighting, but find themselves standing on a huge trap door which gives way to land them both on a web of adhesive-coated cables. Trapped, they finally meet the real museum thief-- Catman!
