Kitty Confidential (Pet Whisperer PI #1) by Molly Fitz

Despite how stupid this plot is, it is really funny and filled with a bunch of crazy characters.This includes our heroine. Stupidity is the our heroine's mainstay, especially when it comes to the P.I. business. In fact, I think the cat is smarter than the human. It's obvious our human doesn't really know how cats operate and expects them to act like humans. She has a lot to learn.
