To support your cat's immune system I suggest our Antiviral formula. I also suggest our Daily Multi Plus to help support his digestion, immune health and overall vitality. Since most processed pet foods are very high in carbohydrates that can aggravate your cat's condition I suggest a healthy whole food gently cooked diet which you can learn how to do in our article How to Feed Your Cat. If home-preparing is not an option you may consider a pre-made gently cooked whole food diet brand such as Raised Right cat food, which you would simply thaw and serve. Our article How to Get Your Cat to Take Their Supplements may also be helpful. Finally, you may be using too much lysine, or one with additives that may upset his stomach. Try this brand of lysine with proper instructions for cats.
