This sounds like another case of researchers looking for something to do. And is it that cats make people schizophrenic, or are schizophrenics attracted to cats?
Ah, who cares? My house cat has a calming effect on me. I’d be less sane without her.
A calming effect? LOL. You haven’t met my cat, DaisyJane, a true brat of a cat. It’s her way or the highway. Vet laughed when I took her in at six weeks old for her first visit. “She’s a tri-colored tabby, very smart and very fierce.” You betcha. She bites me when I don’t do it her way and right now. We have very loud arguments and swear at each other too. “Bitchy Kitty” . I love her madly, admire her spirit,, and she’s a great cuddle when she feels like it.
