hehehe Toby used to do the same for Lily! He would wait around for her to do her deeds, and after she scraped her paw along the side of the box and floor for like 3 minutes, he would go try and cover up her dirt! He's not much better at it though, he spends most his time scratching at the side of the litterbox, and then makes one scoop at the litter. I never understood why neither one of my cats dont' know how to cover their dirt right! =/ Its totally cute tho!
