I love this product. First found in Petsmart, but they do not sell it any longer (Fools). My cat had a cold in his eye so I purchased this product. Within 3 days, he is doing much better. I truly believe in this product.My cat has herpes of the eyes really bad.. and this seems so far the best that I have used in his entire life (12) yrs. And I have been through a lot of products/eye meds.I'd like to rate this higher, but it's not a miracle cure like other reviews I've read. I have to put this directly into my cat's mouth, rather than just putting it on his paw (because he'll shake it everywhere) or letting him lick it up himself. He doesn't really care for it, which I'm not surprised--it stinks! haha. Cat was still sneezing, though, despite this product.Cats hated it...waste of money.We give to a stray cat that frequents our home to eat. During the winter months we give to boost his immunity and he loves it. Helps tremendously.I'm guessing the flavor and smell are too overwhelming for my cat because it smells worse than his wet food. He tasted it for the first time but wouldn't eat the rest in the packet. I put some in his dish and he would just eat around it. Definitely wouldn't recommend for a picky cat. I wish there was a fish flavor.I’ve gotten these before. This one has an off putting smell. Most of the cats refused to take it even if I mixed it in wet food. The kitten was the only one who would eat itCats won’t eat it unless it’s buried in their wet food
