I have been thinking of feeding my 4 cats the same food as my dog (after breaking it into smaller pieces). Specifically Orijen Adult Dog. It costs $45 for a 15lb bag of cat food and $60 for a 30lb bag of the dog food. Looking at the ingredients there really is not much of a difference. The only thing that I worry about is the taurine. Since the dog food is 70% meat I figure that should contain enough. The Orijen cat food does not list taurine as a specific additive so they must be counting on what is in the meat?
