Well not every where just there run. I put a dirt tray in the part they were weeing and pooping, so they stated doing t just on the edge outside the tray. So I put another there, so they poop at the side of that one. I now have 3 trays there but they just keep pooping and weeing outside it. The shed inside is clean and they use the trays there, why are they doing this? There run has been clean for 2 years! arghhhhhh x
