Oh! Oh! I think I qualify!
I have been having issues with Indoor peeing. A Trainer suggested that my guys were confused about the substrate. Outdoors they use a brick patio.
Yesterday I went to the brick shop with a CAD drawing and had them cut 12 bricks 1/2" thick and various lengths. Then, I laid them in a plastic tub to create an Indoor pee spot with the same brick as our backyard. Hah! It has worked for one of them already!
BTW, I had a story all planned that I was building a brick 'step' just in case anyone asked!
