clement..no offence but that method is not always applicable right??
bcoz there are owners who arent at home 24/7 to monitor their furkids pooing all the time as they may have other obligations as well...
i used to have this problem when my baby boy was little...
but i used a pretty useful method recommended by the other forumers here...
if your furkids are used to eating their poo...
then the nex time u see them poo, and you're sure they are going to eat or play with their poo right after they finish their business, hold them back, then cover their poo 100% totally in white pepper...
when your furkids go near their poo, they will sneeze ferociously or even tasted the white pepper....for me this is the method i've tried and ever since then my baby boy have never ever attempted to go near his poo ever again

although this dont work for every furkid also...but this is another alternative
