My cat has conversations with me. When I walk through the door after work, she greets me. I ask her how her day was and she replies. When I leave for work, I tell her to stay out of trouble.
Love it. My cat likes to remind me who owns the house. She always needs this spot on the couch, right were I want to be. Half the bed is dedicated to her because she took it over. She walks into the bathroom while I am in there "ummm, some privacy please..." Nope, it's her bathroom too.
