HELP! My cat, Barney, was sick a couple of months ago and he had a few accidents outside his litter box. Now he thinks he can go potty right by my front door on the tile. I've scolded him, cleaned the area, showed him his litter box again, just to find another potty down there. I've resorted to putting another litter box by my front door and trying to refrain from any more scolding. He immediately used the litter box by the front door. I've had him almost 3 yrs and he's always used his litter box until recently. I have not changed the kind of litter or moved his first litter box from it's oriiginal spot. What else can I do? It's very hard to out think a cat.
