Just my own observances.
You can try Forbid, or any product designed to make poop repulsive, and occasionally those things work well. In my own experience, I have found that when my furkids have too much protein in their diet, that it passes through their digestion
partially undigested, so they smell it as more
food. What I've done is cut their diet with additions that are low calorie, low protein. Things like green beans, or sweet potato cubes, even carrots.
Also, have a stool sample tested for parasites. That has also caused some odd eating habits in my home.
Some furkids that come from 'less than stellar' backgrounds, will often eat their stool as a way to keep their area clean.
Lastly, some kids love to play with stinky things!!
Noselicks to all,
