We really thought he was in his last 24 hours when it occurred to me that his eating habits had started to go down hill about three weeks earlier when I had noticed a slight change in the color of his food. He has always been a finicky eater and has always wanted the store brand version of Purina. So wondering if this could be the problem, I want and got the real Purina version and he started eating it immediately. After he regained his strength I tried to give him some of the left over old stuff right next to the new stuff and he wouldn't touch it. Evidently a slight change in the formula for the food threw him in a total downward spiral.
