I know Lola. I don't trust any of them either. But the thing is, other foods, that I know for sure contain carrageenan have caused Little Cat and Struvite Kitty problems. The By Nature 95 % for instance, and the Merrick Before Grain. On either of those brands LC gets diarrhea and SK regurgitates.
I have to feed them something, and so far, the By Nature Organics has not caused either of them any problems. I DON'T like feeding only one brand, and with Little Cat, I now have her on three brands of canned (one brand one flavor, one brand one flavor, By Nature Organics, two flavors) and two raw foods (Stella&Chewy's freeze dried chicken, rehydrated, Ziwi Peak air dried Lamb). I wouldn't mind a couple more brands for her and another protein, all her foods are chicken except the Ziwi Peak air dried lamb. I'm looking at that Hounds and Gatos now.
Struvite Kitty still needs another couple of brands and she definitely needs another protein. I am trying to think of a way to get my hands on some Rad Cat frozen raw, Lamb. To have it shipped I have to order at least 4 pounds of it. I would have to buy a small chest freezer to store it. That's a lot of money to spend out, on a chance she may or may not like it.
Well I'm drifting off topic here. So hard to stay on topic when talking about what to feed them!
