"Sixty percent of cat owners sleep with their cats, which may enhance their sense of security and improve their quality of sleep" Maybe, but now only between the hours of 10pm - 5:30am, for me anyway.
In my case, it demolishes any chance of restful sleep. She literally walks all over me. She'll meow at the door if I shut the door. So it's either meows or walking. It's a ... nightmare.
It can take a while so be patient. My kitty stopped meowing at night after I do this for two weeks, and has never since meowed at night.
