Mimi Lee hoped to give Los Angeles animal lovers something to talk about with her pet grooming shop, Hollywoof. She never imagined that the first cat she said hello to would talk back or be quite so, well, catty--especially about those disastrous dates Mimi's mother keeps setting up.

When Marshmallow exposes local breeder Russ Nolan for mistreating Chihuahuas, Mimi steals some of her cat's attitude to tell Russ off. The next day the police show up at Hollywoof. Russ has been found dead, and Mimi's shouting match with him has secured her top billing as the main suspect.

Hoping to clear her name and save the pups Russ left behind, Mimi enlists help from her dreamy lawyer neighbor Josh. But even with Josh on board, it'll take Mimi and Marshmallow a lot of sleuthing and more than a little sass to get back to the pet-grooming life--and off the murder scene.
