Darcy poos are awful, at first I thought it was just because of his diet from when he was a stray, but they haven't improved at all with his changed diet. On the other hand, Pepsi's improved dramatically with high meat wet food and the occassional chicken wing, as well as being a lot firmer. I put them into a nappy bag, tie the handles, and put them straight in the bin and I find that this helps to remove the smell quite quickly, or you could invest in a Litter Locker or similar?
