lol, I don't mean to laugh but I know EXACTLY how you feel. Lilly was doing the same thing; she thought it was a toy and thought it would be fun to growl and attack her poop. It was sooo gross and she would get it ALL over the place (including up the walls). This usually only happened at night when I wasn't able to clean it up right away. Now I have made it a habit to get up around 3 (that is usually when she goes) and clean it up as fast as I can. I haven't had any problems in a few weeks. But you never know with her lol. I think it may just be boredom.
