Peanut Butter is almost 13 weeks old-- He still plays in his litter box to the point that I am sweeping up litter 3-4 times per day-- His litter box is clean but he just gets in there and throws litter out-- I had to get him a covered box-- Thinking seriously about getting a clevercat box really soon to contain the mess. Even when i am in the process of scooping and changing litter he will stand in the box and scratch litter out. Its soo aggravating-- I know that playing in the box is normal but when will he grow out of this? Thanks!
