It's Harley Quinn-crazy cat lady! Seems one of Harley's tenants used to be a small-time, cat-themed crook, but now is just a lonely retiree hoarding felines in his apartment. Gross! Harley takes it upon herself to find homes for the "cat burglars," but in trying to get them adopted, she runs afoul of the local pet store, "Men O'Paws." But who's gonna feed the kitties while Harley fights this turf war? And more importantly, who'll clean their litter box?
