I've ordered this Lysine for my cats: they're starting a "kitty cold" - again!- alleluia this brand does not taste as "sour" as other Lysines (even the vet's powder has that awful smell, I can imagine the taste and sympathize with the kitties for refusing it). Pure Encapsulation's lysine goes undetected in their pat√©. You know what that means for me? I can give them Lysine now (and without the fuss) and probably prevent the cat flu virus from hitting base. Plus, ascorbyl palmitate is vitamin C that cats can absorb and because it's not acid, they don't detect it either. I'm so happy! I had to write this review and tell the good news to all those crazy (or not so crazy) cat ladies out there!
