Cat groomer Cassie McGlone tails a killer gone wild over feral felines. . . Cassie's good friend Dawn is part of an organization that's trying to protect a colony of stray cats on the property of a condo community in Chadwick, New Jersey. The residents have got their backs up over the cat invasion, and Dawn has come to Cassie's grooming and boarding shop, Cassie's Comfy Cats, to ask her help in talking sense to them. Not everyone's against the cats. Eccentric Sabrina Ward feeds them and has even created makeshift shelters for them in the nearby woods, infuriating her neighbors. Following a heated community meeting-in which Cassie and Dawn come up with a proposal-Sabrina's body is found in the woods. The police are calling her death an accident, but Cassie smells a rat. Narrowing down the list of suspects may be tougher than herding cats, but Cassie is determined to collar the killer before another cat lover has a fatal accident . . .
