NO cat food! Cats do not produce the enzyme taurine naturally. Taurine is added to their food. Dogs produce their own taurine, and eating cat food will overexpose them to it and cause liver failure. One of my own puppy's owner called me a couple of years ago asking about liver problems in my dogs. I asked her right off if Otis had been in the cat food, as I remembered her cats. Turned out he had indeed hogged down a fair bit,and had high liver results in his bloodwork, which is why she called. I told her to keep him OUT of the cat food and why. Two weeks later, his counts were again normal. NO cat food!
