I've also heard pineapple does the trick. I know it's worked for a lot of other YT members. Spike used to be a poo eater. He would eat his and also Sugar's if I didn't get to the potty pad in time. I used meat tenderizer on their food (same enzyme as pineapple) and it worked like a charm. I only had to do it for a few weeks but he stopped after only a few days I think. I did catch him a few months later and started the meat tenderizer again. After the second round he's never done it again. It makes the poo taste bad so they get out of the habit. I did meat tenderizer instead of pineapple because I had to give it to Sugar as well and he has a super sensitive tummy. Good luck- it's gross but trust me, you aren't alone.
