Everyday, sometimes twice a day, I have to clean up poo poo that does not go in the litter box. Seems one, or possibly more, cats go into the litterbox but hang their bottom over the edge and hit the floor and rim of the litterbox. We cannot use covered boxes since some of the fear going inside of them. Anyone else have this issue? Any suggestions on how to help them have a better "aim"? It's frustrating since I walk into the house and hit with a major odor!
