Hmmm...I don't know why he would go for butter, but maybe when he got it once, then he doesn't want to stop! Marta got up onto the table once, now she tries to get up there all the time when she's bored.

What I do about that is just make sure all the chairs are pushed into the table so she can't get up, and I also don't leave food out there (although I still had a bottle of olive oil up there, which strangely enough ended up on the floor of the livingroom yesterday!!! There was olive oil all over the carpet! I think our kitty Seine must have knocked it off the table...). The only suggestion I have is to just put the butter somewhere else, like in the cupboards or something. I hope he gets over his addiction soon.
