I have to agree with all above - STOP MOVING THE LITTERBOX is the first thing; and, yes, a vet visit may be in order for the inappropriate relieving.
As far as the "crazy" behavior. That's not crazy. There is a wall in the family room that Pinot just cannot tolerate. I don't know what it did to her, it must have been when we were at work, but she'll be standing there, and all of a sudden will jump up and attack that wall. BAD WALL!! She also gets a little loud and darts around when she has to go use the litterbox (and I'm not talking about peeing) - I'll just look at her and say, "go use your box, would you?". She does after a bit.
All cats have the crazy gene that comes on in spurts; part of being a kitty! We wouldn't have it any other way!
