What's the Name of That Book??? discussion

This book is about a cat who stalks a recently widowed woman. The cat is the woman's deceased husband. The woman deliberately serves unhealthy food to the husband so he will become overweight and unhealthy. Then the woman comes home when she knows the husband is cheating on her. Her appearance causes the husband to have a heart attack and die. This is her goal. Now she lives alone with her pet parakeet. She meets a new man. A cat begins stalking her and attacking her and her new love interest.

I'll read it!!!!

This sounds interesting, I don't know what it is, though.
