Aren't you being nawtee today!! LOL!

About Sammy, is this the first time he has peed like that? If so I would think it was just that potent catnip and I'd make sure he wasn't it around it again. It won't take much to start a bad habit.

As for the humping, Ripley used to get amourous with an old Oscar the Grouch handpuppet. It got to be a problem when he was dragging it out in front of company so we buried Oscar at the bottom of a closet. After that I woke up one morning to find Ripley humping the wadded up blanket beside me on the bed. He would do that every once in a while for a few years then finally stopped. I guess he needs kitty viagra for it now because with old age all the humping stopped.

I'm sorry I don't have any advice but maybe someone else with a more um, virile cat can help. Good luck.
