I'm switching Pepper into different food, His dry kibble stays untouched unless I mix it with something, I'd love to try to find something he'll like to eat... I just got a bag of Science, it's still sitting in the car as I'm at work. I did read the label and didn't see any by'products? It's that improved one in the colorful bag... But I read the reviews stating it's crap

Now I'm really confused...
