I have been struggling with this situation for over 3 weeks. He literally plays with the litter and searches for his feces and kicks it outside the box and keeps playing with it around the flat. I am seriously considering giving him up. Other than the cost of sand that I have to add everyday. I have to vacuum 3 times a day!!! Please, if anyone knows how to deal with this issue please help! I use the foam mat that captures litter but he is determined to spread the sand everywhere to the point that he fills it up!!!!
