Caraneengan is used in lab rats to promote inflammatory diseases as well as many other diseases,so I stay away from canned foods that contain it. However my cat was never diagnosed as having Ibd, she was having constant gas and diarrhea from eating foods with caraneengan in it. The minute I took the foods away with the caraneengan in it , she was better. It is sad that these companies do not want to address the problem, but when owners start realizing it, the'll stop buying these foods.. Wellness , merrick ,Bf ,taste of the wild and many more companies are still using it. Hounds and Gatos doesn't and is rated one of the best cat foods out there,although they use gums, it is still better than carraneengan, As for the Stella and chewys, soak in warm water for a minute or so, then add to the canned food you are using. Some of the my cats love it soaked and "tear" it apart when they eat it just like in the wild. Wild calling is another brand to try but I always mix with another brand for variety. They do use brewers yeast in their food, I'm going to ask the store owner who I buy from and see what she thinks and will let U know. Give hounds and Gatos a try and mix some soaked Stella and Chewys in , start out with a little at a time, and see what happens . Good Luck !!!! U may of found a CURE !!!!!!!!!!!!
