No idea, but I have tried Deter and anything to make it undesirable to turn around and chow down. It totally grosses me out. Kylie can not help herself and if I don't pick it up in time she goes for it like candy. ew!

If you find something that works let me know. It is worth a try!! Deter seems to work but on some occasions I still find her back to old habits. I hope she grows out of it.
