We were told he was mostly there with litter training.
Well, he's not.
He's put in the tray when he wakes after a long nap, after he's eaten and when he seems to be mooching in corners.
But it's just not doing the trick. We have 2 trays in the living/dining room in the areas where he was mostly going. And another tray on the landing upstairs.
Still he poops in the corners, sometimes just next to the tray. Or on DH's shirts. Or in his wardrobe. Or under DD1's bed.
