Review on 🐱 Enhance Your Cat's Immune System with Dr. Bill’s Feline Immune Support: A Premium Pet Supplement with Colostrum, Beta Glucan, Lactoferrin, Zinc, Coenzyme Q-10, and Bifidobacterium by Stephanie Webb

I had such high hopes for this product after reading the reviews. Both of my cats sneeze (one longer than the other) and I've given them lysine but it didn't work. As soon as I gave my cats this powder with their food, one of them immediately (within a few minutes) vomited and vomited 8 or 9 times until there was nothing left to induce vomiting. I thought maybe it was an accident so I tried again the next day and the same thing happened. This was only with one of my cats so I suspect he is allergic to something in him even though he is 12 and we have never had an allergy problem. The same cat is a very picky eater and he ate the powder so I gave him one star.
