Natural Balance issue?? A few months back I switched from Taste of the Wild to Natural Balance food. They have done great on it. I switch them between the premium small bites in the blue bag to the small bites with duck in the yellow bag. Well this last time they ate the blue bag there poo started getting really runny so this time I got the duck one and there poo is a little harder but they are pooping alot more and its dark black almost tar like. Anyone else have this issue with Natural Balance? |
