I still need to try the meat tenderizier because none of the other stuff worked. Joey is 2 years old and Izzie 5 1/2 months and they are the only one who do. Emilee will be 3, she doesn't, and Gidget is almost 17 months and she doesn't eat it either. It is so gross. I was told they eat because of them pooping where they are not suppose to, because they were missing some vitamins and minerals and also because they smell the food in they ate and like it. Yuk..
