I know that tuna is problematic, and I really debated with myself about it, but I will admit that I got some of this food to drizzle over or lightly mix with raw when someone is reluctant to eat (new protein source, blander protein source, etc.) I'm talking about maybe half of a 3 oz. packet, divided between six cats in the course of a day, if that. It has worked well as a sort of "seasoning," and has been particularly helpful with Jenny, was the most reluctant of all the cats to accept raw. One thing I do like about it is that the consistency makes it difficult for the cats to pick out little pieces and leave the raw food behind. I have nine pouches left, and am hoping I won't need any more when they are gone. I'm doing some research now, to see if I can find something more suitable if more "bribe food" is needed at that point.
