I had a cat who talked and howled, a lot, too. I understand your frustration with it. Spotty lived to be 18 years old and I swear sometimes, she even talked in her sleep. She would deliberately go into a different room and YOWL for me to come in to pay attention to her. My only possible solution is to not reward her for the behavior. When she's talking, ignore her. Only pay attention to her when she stops talking to you. Granted, this didn't work on Spotty.... I just learned to live with the noise. I wish I could hear it again. Spotty has been gone for two years.
