Maybe I should rephrase my original post. I was trying to sum up a much longer conversation. Potatoes are contributing to yeast. So even though we weren't doing grains that some more starchy veggies could also be contributing to yeast and the food we were using was quite high in potatoes

could totally be something else causing the eye goo but heck it's gone after switching tho food and they LOVE the new food. I tried to follow the rules and just mix a little of the new food into the old food and they individually picked only the new food and left the old food strewn all over the floor.
