If Simon was a girlkitty, I would rename him Sybil (keeping with the "S" names) as in the movie "Sybil" with Sally Field, where the character had multiple personalties! Simon has a love/hate relationship with his Daddy whenever Keith goes out of town for any amount of time (he was in the UK for almost 3 weeks). When Keith gets home Simon will love on him and then hiss at him in a New York minute! And of course since Simon is a Momma's boy, that doesn't help things out one bit ... LOL!
Is this unusual?
