Jewelsy - They WILL get over not going outside. The scratching and meowing with the water running most likely means they hear something that irritates them. (Plumbing can make noises that we do not hear, such as whistling, screeching etc.) Their "accidents" are most likely their way of telling you somethings bugging them. If you don't already change the litter every two or three days, but do scoop it daily, try cleaning the box and changing the litter more. If the box is now in a different space, the odors may be more noticable to them. When I moved to this apartment, I had to clean/change every 2 days, now i do it about every 3 days. If I didn't or don't Joey goes to wherever I am, hunches down and acts like he is going to pee. I say OK OK I'll clean the box, I do it, he waits and then uses the box.
