Do you shop at your local independent store? Different stores will carry varying types of brands, and they certainly know their stuff, including ingredients, so you may find something that meets your criteria there than big box stores. Some independent stores will even offer a few cans as samples or take back unopened cans, just inquire what their return policies are, including commercial raw.
Or, you may simply have to lower your expectations a bit in canned versions of food. If you plan on rotating brands, it may not really be that big of a deal that they get some gums or carrageenan every once in a while, and not all the time if you're worried about finding the "perfect food". Imho, there is no perfect food, lol. That's why I try to rotate brands and proteins, so my cats can have a more balanced diet. But do what works for you, too, don't stress so much over it.
I have found from the yahoo raw cat forum that many cat owners find raw pork to be one of most cat's favorite protein, along with the poultry types like your Cisco. I buy pork from the supermarket, a human grade meat with some fats, which cats metabolize better than carbs. Hound and Gatos have canned pork (pate), which seems to go ok with both my cats. But they had it their way, they would eat rabbit, venison, duck and brushtail (the most expensive proteins, of course) all the time! Weirdly, they both do not go bonkers for chicken or turkey as much, whether it's canned or raw. Only exception is Tiki Cat and Weruva's fowl ball. Something magical about the broth, I think.
Hope you get more suggestions from others!
