Thanks for starting this thread!

Our visitor cat has been here for a few weeks now. He has started pooping outside of the litter box over the past couple of days. He only seems to be doing it once per day. The poops are pretty solid with a little bit of... "extra liquid".

It's all been in my dining area (which is being used to just store stuff that I've gathered and have no place to put or no use for).

The first couple of times it was on a trash bag that has a blanket in it. I didn't find the poop for a couple of days (I never smelled anything, it had to have happened some time while we've been out.). I picked it all up and disposed of it. This was 2-3 days ago. Just now, I found a poop inside a box of recipes, letters, cards, etc.

I am just hoping to find a way to curb this behaviour quickly. What I've done so far is crated him, cleaned the litter box TOTALLY, and went back to clay litter. What I plan to do is isolate him in the bathroom (where the litterbox stays), there was one more thing but I forgot what it was.

Any suggestions would be immensely appreciated!
