J.C.
Hi C.! I'm sorry to hear that he's acting out like that. Has there been some change in his life that he may be looking for some positive attention? That happens sometimes, where they act out in hopes of getting attention. I know you don't want to reward him for peeing all over, but maybe you can make him a chart with stickers and he can put a sticker on the chart for each day he doesn't pee on the floor, and at the end of the week, he can have a special treat (ice cream, a trip to the dollar store, McDonald's, something cheap). Good luck!
