Our 9 week old shelter adoptee Henry had problems using the floor after I moved the litterbox about a week ago. So I leaned like mad and put the box where he was going which was the bathroom and bought another box and placed that one where the original box was. We have 3 litter boxes in total for 3 cats. Henry was doing great now over the last 2-3 days he is back to defecating anywhere he pleases. Under furniture, on the floor and he is using the litter box. Can someone tell me what could be going on?
