@99reasons4truth I dated a guy once who, after I brought him to my house to watch a movie, my cat refused to be around me until we broke up. It was a nasty break up, and I found things out later that made me go, "Ohhh...the cat KNEW!"
Also, all of our cats and dogs can tell when I've had a seizure. They try to take care of me for a few hours. Which isn't "bad", but it shows they pick up on things.
