Meow is for Murder, Petsitter Mystery by Linda O. Johnston, published 2007 by Berkley
Finished that cozy mystery, Meow is for Murder, and couldn't have guessed ahead of time the person who "dunnit" or how those two Bengal cats were used to find the murderer. Clever little plot, although the deal that petsitter and lawyer Kendra makes with a suspect is unusual and somewhat unrealistic, I thought.
The suspect, Amanda, is charged with the murder of man who has been stalking her. Amanda is the ex-wife of Kendra's current love, Jeff, and a bit of a stalker herself, always showing up at Jeff's door with various and sundry requests for help and assistance. She promises to stay out of Jeff's life for good if Kendra, an amateur sleuth on top of everything else, will find the real killer and get her off the murder hook.
Here's the weird part. Amanda signs a "legal" and "binding" document saying she will be out of Jeff's life forever if Kendra proves her innocent.
In the end, Kendra finds that Jeff may not have been worth all the trouble after all and accepts a date with, here it comes....., a vet that she meets on one of her other lawyerly cases. Now, like so many of the mystery heroines these days, such as Stephanie Plum in Janet Evanovich's books, this main characer has two love interests to add sauce to the mystery.
Catch Kendra in the next book in the series to see how the new guy works out. That's how the mystery series sometimes works - a thread of romantic intrigue leads you on to the next book. Curiousity doesn't always kill the cat, but it sure makes some writers Fat Cats.
