Please excuse me if this was posted incomplete. Sadie had a mega hairball which also caused to her to become constipated. End result is that she will pee in the litterbox but will not poop in the litterbox due the pain she was experiencing from being constipated. In fact, she hadn't pooped for two days and as soon as I put down some newspaper on the floor, she pooped. But, I want her to go back to using the litterbox for that little duty. Does anyone have any suggestions on how to retrain her? Am going to keep on giving her pumpkin in her food for the next couple of days just to make sure she's cleaned out.
