But right now, I am beginning to suspect if ET's scratching had anything to do with the chicken I recently started him on. He may be allergic to it. I gave it to him when I 1st got him, he seemed to vomit and have soft poo each time, so I stopped. I started giving to him again 1wk ago after all the scare about carrageenan and Fussie Cat Chicken doesn't have carrageenan or guar gum. Will see if he will stop scratching if I stop chicken or was it Wellness Core Turkey & Duck that is giving him the itch? Will eliminate these 2 food gradually to see which causes the itch.
