Harley just confuses me. He's one of my 3 that is allowed to go outside but he stays around the house (we live at the end of a dirt road and traffic...is, well...just us!). He only goes outside during the day when I'm home and spend most of his time being lazy in the sun. But, after a few hours he will paw at the storm door to be let in. Once in, he walks straight to his litterbox (that I just cleaned!), uses it, and wants back outside. No stopping at the food dish and he does have water outside. What I want to know is WHY???? He has the entire 5 acres to use as his litter box! And, how does he know that I just cleaned it?? It never fails.... it's like he has a sixth sense "Oh, I sense a clean litter box...must go dirty it!"
