Our 5 month old boy ended up sick a few weeks ago and had a few accidents around the apartment. That was forgivable, but he still is pooping outside the box once every night. Twice he's peed outside of the box now. I don't know why he would be doing this. We've been saturating the [wood] floor with Nature's Miracle spray after every time he goes, but it doesn't appear to stop him. I don't know what to do with him to get him to stop. Suggestions???
