So, I was looking at my cat and I noticed a little white patch just under her left back leg. After picking through the thick fur, much to my surprise, was a tag! I shaved that little patch and there, right on the cat, was the ingredients. Well, sir, I can assure you that all cats are not pure. Mine is only 37% feline, 33% water, 5% hydrolyzed protein, and 25% xantham gum.
