I'm sorry to hear that he's having more problems again. My Pearl is allergic to grains and if she eats them then her lips and chin will break out. She has Eosinophilic Granuloma Complex which can be caused by different things but in her case it was her diet. I've been feeding everyone Innova Evo for several years now and all of my cats are doing well on it. Hermes may even be allergic to the brown rice in his food. I hope you'll be able to find out what's causing this. Good luck.
