Spook likes to pee...right in FRONT of the litterbox (hence why I keep it on the tile ) if it isn't clean to her satisfaction. I *try* to scoop every other day but sometimes it gets forgotten for a day or two...and it isn't long until I KNOW that the box needs to be cleaned

At least she is predictable, and doesn't pee anywhere else. Remus has his days of knocking things off of my desk or shelves but other than that he is pretty mellow.
