Yes, it sounds like you are having to go through the nuisance of having to put a locking handle on the door. I had a team that kept me constantly cleaning. The Artful Dodger could open any door or drawer in the kitchen until I put clips on everything, but he never peed in there. Loki came along and did that. In fact, Loki peed on everything in the house and it's amazing, and horrible, that he always peed on the most difficult things to clean. If he peed on the stove, it would go in the vent into the oven. If he peed on a door, it would be on the hinge. Out of the entire house, I used to have one small closet in which he'd never peed, and every time I used it I'd sigh with relief that there was one spot that was mine, all mine. Then, one day I was putting something away and put my hand very gently against Loki and told him he couldn't go in there. In the split second it took me to straighten up, he had whipped inside and peed up the wall. He wasn't smart, but he was very determined.
