I have a 9 month boy kitten and he is litter trained. He has been using his litter normally since I have had him but in the last three months he has, five times, taken his poo out of the litter box and smeared it across the floor and then left. I thought he may have accidentally stuck on his foot or something but it clearly has been played with. Does anyone have any advice on why this is happening and what I can do?
