Is the moon full? I don't know what gets into them sometimes. It is just like you say - they go ape$hit for no apparent reason - probably just because they can. Plus - Remus is still a kitten - right?? Maybe he still has leftover hormone from his bit removal. If it WAS a vasectomy he had - he will still HAVE his hormones the way I understand it He just is sterile. oh MY! He may be an eternal kitten!
