After several years of dealing with Chris pooping on the floor, we now have a new bad cat giving us the same trouble. Chris pooped his way through three homes before finally stopping when we moved into our last home.
Puck started pooping in our current home well over a year ago when we bought a new sofa for our enclosed patio. He surprised us by pooping on the sofa and we naturally blamed Chris. The pooping on the sofa happened a few more times and we eventually figured out that Puck was the culprit.
We concluded that the sofa was too close to the litter boxes for Puck’s comfort level so we moved them across the room. That ended the pooping, for awhile, but we still kept a cover on the sofa as well as pillows and cat toys to discourage pooping.
Things went pretty well after that with just an occasional “accident.” I don’t remember exactly when the pooping problem started again but it may have started when we brought Floki home last July.
A new kitten in the house may have caused some trauma for our timid Puck but Floki was traumatized a little too. He didn’t enter the house and take over like Chris did. Puck and Floki also get along well now, although they do a bit of roughhousing now and then.
I tried changing the litter. I tried scooping the boxes as often as needed. I tried adding another box. I even tried adding Dr. Elsey’s Cat Attract, which partially worked for Chris. Nothing worked for Puck.
I’m sorry for the graphic picture below but you can see what I am often presented with when I go onto the patio. The brown stuff in the box is the Cat Attract which guarantees 100% litter box use. Perhaps I should send them this picture.

By the way, we solved Chris’s problem by moving the litter boxes from various rooms to the same place. This allowed him to pee in one box and then poop in another. I don’t know what to do about Puck
As I wrote the last sentence, I noticed a strong smell of poop. I turned around ans saw Puck just now pooped on the floor while I was busy writing.
