Review on Rx Vitamins Essentials for Cats - Multivitamin & Mineral Supplement - Boost Wet or Dry Cat Food - Powder 4 oz by Amy Monson

I purchased this supplement for my aging cat after she started eating a quart. It's easy to use and when mixed with tasty food my cat eats it right away. His mood has improved, as has his energy level. HOWEVER, my cat, who is very sensitive to allergens, had a terrible reaction to something in this product. Just a few days after I started, his skin turned so red I could see it through the white fur. He has also developed a number of hotspots and . I gave him the product for about 3 weeks when I realized what was happening and within 24 hours of removing the supplement from his diet the redness had noticeably reduced. I sincerely believe that the product is not the problem, but if you have a cat that is severely allergic to reactions like my cat, then you should choose a different product.
