Hi Janice:

Poor Skuffy -- he might be jealous. But it might be something simpler. Do you have enough litter boxes? I have three cats and one started pooping on the floor when we moved to a new house. I added another litter box (so there are now three boxes) and changed litter brand and that did the trick! Cats can get really picky about their litter boxes and Skuffy might be objecting to the increased number of litter box users! Good luck!
