It works :))
We're really happy with this. My cat has had on and off problems with his eyes for years. Despite all efforts he kept getting problems. Since giving him this product with his food ( took him a couple of feeds to get used to it ) he's not had a problem for a long time now and seems happy and healthy

My fussy cats went crazy for this wven tried eating the little spoon. Appears to be making some changes with our more problematic cat and her eyes early days to fully confirm but they definitely love the taste thier new treat haha

Great stuff for feline herpes; plus, a cautionary tale and a solution to a problem
I purchased this as a replacement for another brand (Viralys) that I had been getting through my vet. One of our kitties had a "cold" when we adopted her. That "cold" just wouldn't clear up. She had a weepy eye and sneezles for weeks. When we took her to the vet, the vet said it was kitty herpes and prescribed the Viralys (at $30 a container). It's l-lysine in powder form; you sprinkle it on the cat food. There is no cure for feline herpes, but l-lysine helps clear up the symptoms. (For those who want to know how l-lysine helps, The Cat Doctor & Friends in Santa Clarita says, "We use L-Lysine to fool your cat's herpes virus into self-destructing by using L-Lysine, instead of another amino acid Arginine, when making new copies of itself. This decreases the amount of herpes virus in your cat's body and hopefully eliminates clinical signs such as sneezing or squinting one eye and reddish brown discharge. Green or yellow discharge from your cat's eye or nose is probably not feline herpes and deserves a veterinary visit.") The Viralys l-lysine powder not only worked great, clearing up the weepy eye and drippy nose within a remarkably short amount of time, it was also loved by all our kitties. (The vet said it wouldn't hurt any of them to eat it.) However, at $30 a container, and with the stupid mistake I made that wasted half a container (see below), I wanted to find a less expensive alternative. And I did. This product, the Tomlyn Scientifics l-lysine, seems to be identical to the Viralys, and costs half what my vet was charging me. My one concern was whether it would taste as good to the kitties, and it does indeed seem to. == My Stupid Mistake and How You Can Avoid It == When I first got the Viralys from my vet, I made a stupid mistake. I used the little scoop that comes with the powder to sprinkle the lysine powder on the cat food, and then I used the scoop to stir the powder into the food. Then I returned the scoop to the container. Those of you who are familiar with good sanitation practices will be able to predict what happened next: after a while, the tiny crumbs of cat food I had inadvertently transferred to the container gave birth to new life. In a few weeks, I saw suspicious little clumps and balls in the powder. I threw out the rest of the powder rather than risk making my kitties sick. After thinking about what I could do to prevent wasting my kitties' medicine (and my money), I realized the solution: put the powder into a shaker container so it never gets contaminated. After shopping around, I purchased the Kaiser Bakeware La Forme Select Sugar/Spice Shaker Set (available here on Amazon), which is just the right size for the powder. I'm using the shaker lid with the largest holes. Now all is well.

Very good product, works perfectly for my cat
My cat, Pickles, is a low immune cat. She got sick and eyes infection (chlamydia) very often for the first few month I adopted her. The vet said the chlamydia will come back every now and then and it won’t go away. I looked up what would help, found this product with good reviews and wanted to give it a try. Since I’ve started using this product for about 3 months (one scoop in the morning almost everyday sprinkle on her wet food or mix with a little bit of water in the wet food) she hasn’t got the eye infection at all since. Her eyes clear up and seems so much healthier than before. Will definitely order again. Took about 1 month to arrive from Canada to Australia but worth it. (Hopefully I don’t exaggerate like I thought about all the reviews before)

Works great!
This worked amazingly for my kitten!! She was constantly drooling, had a lot of boogers all the time, and her gums/lips looked super irritated . I used this for about a week and it all went away, she is doing so much better now and she hasnt been drooling or getting any boogers at all. I was so worried but im so glad i trusted this product and now she is all better.
