driver8 - firstly let me share alittle insight on shelters who feed non hollistic/lower 'quality' food. This is because some are given or sponsored by companies to carry and feed their brands. Because shelters are driven by donations, this courtesy is readily accepted by shelters so that they can operate. Please stop throwing shelters into this because it is not what this is about is it?
I don't know if any of us are going to really satisfy your request. Based on my own personal experience, and the loss of some of my pets in the past due to poor nutrition I also jump on this so called bandwagon of educating. It may save alot of people some grief.
