Hi MC---Please note that Halo Impulse and Vigor both contain Agar-Agar and since learning about this ingredient (from you),
I have stopped serving it. Perhaps you could note this fact on the list. Also, there is another brand of Cat food which has some Carageenan free recipes and that is Petguard although I haven't tried it yet. We are impressed with the Thrive--it is shredded and our cats normally dislike shredded anything but they all eat the Thrive. It is impressive.
