She is 3 moths old. I never let her poo or pee in the kitchen. When it happens is when I am not there in the night. So there's no point in punishing her 'cause she doesn't know by then whta she has done wrong. Even though the other day I was very firm when she peed on the kitchen an told her Outside! and took her outside after a few minutes she was back scratching the door. By then there hasn't been any problems since then. When she pooed those 2 times there wasn't anybody there and she managed to get through the door. Now I close the door and never leave them abit open when she's there.
