    GREAT FOR FELINE HERPES! LYSINE SUPRESSES THE AMINO ACID ARGININE, RESPONSIBLE FOR FLARE UPS!!!
    I work w/ my local VSA ( voluntary services for animals). I took in a few kittens that’s eyes were almost completely shut with crust & their little noses were covered in crust & mucus. A pitiful site 🙁 . I quickly took all 4 to the vet within 24 hrs. WELL, after they said it was “Feline herpes”, (an upper respiratory infection that doesn’t go away but can be controlled) IT ended up costing me close to $800!! With Vet costs, testing costs, & the “Wonderfully expensive” medication they gave me for Each cat, That helped some but not much!! They had liquid meds, meds that had to be put INTO their eyes like 4xs a day, & some other antibiotics. It was awful , & seriously it didn’t help much at all. It lessened it some, but they needed the meds constantly! I looked on the Internet for any info I could find & found out about LYSINE !! I really thought it was a bunch of “bull” but was willing to TRY anything! I 1st bought a paste & a gel- the cats hated it. I then bought this powder. I mixed it into wet food ( not too much or they taste it!) & they ate it! After a week I noticed all their symptoms were really improving! I had STOPPED the Vets meds as the cost was killing me & not really helping them. After a MONTH all the cats were totally better, no crusty gooey eyes, no crusty nose, sneezing, ALL GONE!! I was amazed!! I studied it more, the use of L LYSINE & it’s effects. It surpresses what makes the Herpes virus flare up in the system, so taking it on a Dailey basis means you won’t get the flare up & the full blown symptoms! It also works in humans as well. I kept the kittens & have given them forms of LYSINE for 2 yrs now & they have NOT had another flare up since! If I stopped it for a few months, I noticed some sneezing & gunk in their eyes in the 1st year & quickly put them back on it! With 5 cats ( I had a 3 yr old when I took these in, she caught feline herpes from them as well!) it’s kinda hard to make sure each one gets 250 – 500 mg Ea. When they eat out of each others bowls! So I just put a scoop into 1 3 oz can of wet, feed them 3 cans & it works great. I tried the TREATS, most cats don’t care for them, also many brands you have to give each cat like 10 treats 1-2 x a day! Woa! Or another brand the treats were huge! Only 2 a day because they were the size of a golf ball! Lol. So, the cat powdered LYSINE works good, it’s flavored mixes well in food & good to start on. I had no luck putting this on DRY food, I have heard many ppl do that but my cats wouldn’t eat the food & most just fell to bottom of dish/bowl. I also bought & use HUMAN grade LYSINE 500 mg tablets & crush them up w/ a spoon & mix into wet food. This is VERY cost effective! It taste stronger than this flavored powder, so use a good wet food to mix with & you wont have a problem. My cats got use to it fast. You can also buy LYSINE powder in BULK on here, it’s human grade & already finely crushed up. It works GREAT & cost MUCH less. Plus I like that it’s “human” grade. I now can skip months at a time with no LYSINE & they still get no flare ups. This LYSINE is a God send! I recommend this powder if starting out, it’s flavored and cats will take it well. But cost wise, the pills, tablets, capsule at your store or on here ( cheaper!) are strongest & the best I’ve found( crush up finely) . bitter, but cats really don’t “taste” bitter I’ve heard. Either WAY or BRAND you choose it will all but cure your cats of the virus, you won’t have huge vet bills & expensive meds that are worthless. 5 cats taking LYSINE on & off for 2 yrs and they have NO MORE SYMPTOMS & are very happy healthy spoiled kitty’s… So please do yourself, your wallet, & your cats a favor & put them on a LYSINE regimen of 250 mg a day OR – 500 mg 1-2 x’s a day for a flare up or to start off with. Once symptoms subside, you can stay with 250 mg a day to keep them away for good! Btw, In order to replicate & cause FLARE UPS , in humans & cats the herpes virus needs “ARGININE” another amino acid such as LYSINE . when LISINE is taken at higher doses, it prevents the amino acid ARGININE from over producing & hence preventing outbreaks of the herpes virus. So just check your pets FOODS, TREATS etc for any ARGININE ( L-ARGININE ) in them as this will ADD to your problem!! There ARE foods with this in the ingredient list I’ve found, so just FYI to be safe. Hope this helps someone with the problems I went through & learned from along the way!! 🙂 Jenn ~

    Works great
    Good product. I give this to them everyday, and have noticed my cats sneeze way less, and it helps with their watery eyes. I also like the fact that it is fish flavored. I have one cat that is a very picky eater, and will not eat anything but dry food. As long as I mix this in with his wet treat he will eat it.

    READ THIS BEFORE BUYING – Kitties love the taste and eat it easily – Good immune booster too!
    Our kitties were sneezing and probably caught little “kitty colds” when the cold season came. We got them this supplement to help their immune system and it’s worked great! The kitties pretty much love the taste – or at least don’t mind it. One of them even tried to eat it directly out of the container, so if you have picky kitties, I’d recommend giving this supplement a go! It smells fishy like cat food, so that’s probably why they love it.It’s still pretty cold outside and since our kitties started taking this supplement daily, we haven’t heard them sneeze any more or seen any runny eyes or noses!Give this a shot!

    My vet recommended
    My vet recommended this for my car with a compromised immune system. He said to mix it in the dry or wet food. My other 2 cats want to eat out of the jar though! Putting the powder in their food has turned into treat time basically. Totally recommend it. Helped with their health and even their fur shine/ quality. Plus, they love it and it’s safe!

    Easier and More Economical Than the Gel
    My Lilith has feline herpes and gets runny, irritated eyes because of it. She’s had a lot of eye issues because of this virus. She had several sequestra due to it and we finally had to get her a corneal transplant as the sequestra had eroded her cornea so much. Yeah, we love her! :DHer eyes are constantly irritated. Antibiotics and creams fix it for a bit, but it comes back within 2 weeks of stopping them. Can’t keep her on antibiotics all the time. It’s just this pesky virus!I used to use the Viralys gel. And although she accepted it, she got tired of it after a while and it was frustrating trying to chase her down twice a day to give it to her. But the lysine really does seem to help. It hasn’t completely fixed the issue, but it’s the best thing I’ve tried so far. And it really alleviates her itchy, runny eyes a lot!Trouble was, she will only eat dried food, so it would’ve been impossible to mix the gel in with it. So what I do is to mist the dry food with a water bottle (just a gentle misting will do) and I sprinkle this on it. Then I mix it around in her bowl to get it to stick evenly to the dry food. I feed her once a day with enough dry food for the day (she’s a nibbler and eats a little at a time throughout the day). I coat the food with 2 scoops of this. In the beginning I ground it up with a mortal and pestle because I was afraid she would lick it off. But I’m going to stop that now as I think she’s gotten used to it. We have 2 other cats who will only eat wet food. So she does have access to other foods, but she still prefers her dry food with this sprinkled on it.It’s worked out great! She accepts it and I no longer have to chase her around and coax her to take her medicine. And it’s A LOT more economical than the gel! I’ll definitely be buying some more for her.If your cat will accept it, the powder is the way to go!:)

    I was recommended to buy this product as my cat had watery eyes and sneezes frequently. After taking this supplement, all is well. I give it to both cats and they liked it maybe because of the chicken and fish flavour.

    My girl was having unexplained runny/stuffy nose and sneezing. Had taken her to the vet and they couldn’t find a reason except she is old. So I decided to try this stuff. It’s been about a week and there has been a huge difference!! No sneezing, no snot! Glad to see her looking better.
