Never fails to work!

Reviewed in the United States on May 13, 2022

Size: 120 Count (Pack of 1)Color: Original VersionVerified Purchase

Years ago a vet told me to use L-lysine for a kitten I found in a ditch that had really bad crusty eyes and a sneeze and cough. I tried it and it worked! Down the road a bit I found this product and let me tell you that my house always has a bag on hand. If your cat or kitten is suffering with a cough,sneezing and/or crusty eyes,this product WORKS!! Even just recently my adult cat lost her voice and was constantly sneezing,I use dust free litter and knew it wasn’t that and she wasn’t sick but spring was in full bloom so even though she never goes out,I started her on this product. Within 3 days she was better,5 days much better,a week she was back to normal. I kept her on it for a total of 10 days and none of the symptoms came back. I also gave it to my very senior cat back in the winter when she had a nasty upper respiratory problem… she was nasally and wheezing. Same thing… within a week all symptoms were gone. I kept her on it for another 5 days just to be sure. They love the taste and texture of it. It’s sort of chewy and easy to break in smaller pieces,even though it’s already small,in case you like giving them smaller pieces of food. There’s no need to worry about breaking it up if you don’t want to. They ALL love it! I love that it works without an expensive trip to the vet. You won’t be sorry for trying this product!

Mom's Opinion

My Cat Won't Touch Them But Do Work Tip at bottom

Reviewed in the United States on March 20, 2024

Size: 120 Count (Pack of 1)Color: Original VersionVerified Purchase

I got this VetriScience Lysine Plus for my cat and I can't get him to even touch them. My cat is 12 years old and deaf. Usually he loves his cat treats but he won't touch these. My cat has been sneezing like crazy and the vet told me to try this first. So I ordered it and he won't touch them. I have tried crushing and mixing into his food, but then he won't eat the food, he can definitely detect it in there. I have tried so many different ways but nothing is working. I plan on trying to pulverize it and get it to a liquid state and try to pour in his mouth, that's the only way I can figure out him to get it. I know once he gets it into his system he will start to feel better.

I took away one star on the fact that not all cats like the taste. Comes packaged in a nice re-sealable package and cute shape. Thought for sure he would love them but guess not (he eats everything else though). Came extremely fast. I would definitely recommend it, just hope I can get him to eat it.

UPDATE: If you can't get your cat to eat this, here is a little tip:
Break it up tiny or crush the chewable and put in just a tiny tiny amount of water and mix then let sit and dissolve. After about 30 minutes and it dissolves you can use a medication syringe and put down cat's throat. If you don't have a medication syringe you could use a spoon or medication cup to pour down cat's throat. This is how I got my cat to take it and since giving him the first one, he has already stopped sneezing and looking better.

Lysine Price Comparison

Reviewed in the United States on February 14, 2012

Size: 120 Count (Pack of 1)Color: Original VersionVerified Purchase

Executive summary: This product is twice as expensive as the 6.35 oz Enisyl-F Lysine product for equal doses.

I compared the 6.35 oz Enisyl-F Lysine with this product, Vetri-Lysine Plus, 120 chews, 5.29 oz. At the time I bought both, the Enisyl-F Lysine product cost $12.00 and the 120 chews cost $16.81 (free shipping on both). The only way to effectively compare prices is cost per dose. This required counting the number of chews in the Enisyl-F Lysine product: there were ~430 chews in the 6.35 oz package. Since the dosage is 5 chews for 250mg of Lysine, it works out to 86 doses, or 14 cents per dose. With this product containing 120 chews, the dosage is 2 chews for 250mg of Lysine, so 60 doses. That works out to 28 cents per dose - twice as expensive!

Having said that, I still like having both products around, but I mainly use the Enisyl-F Lysine since it is half the price. If my cat is having a bad day with his eye weeping, it's easy to also give him a couple of the "120 chews" to boost his dosage. My vet said that 250mg is actually too low for weepy eye problems related to herpes, and recommended at least 500mg per day. He said there was a study that 1000mg per day works even better for eye problems related to herpes, but I feel like that's a bit excessive. So I put a handful of these chews - 5 to 10 - in Yuri's food and maybe boost it with a couple of the other chews as necessary.

I only rated this product with 4 stars because I'm not sure how much Lysine is actually helping with weepy eye. It's one of those problems where there are good days and bad days, so it's hard to tell how much it helps. But it seems to be a little better with Lysine, so I keep my cat on it.

Update 9/27/2013: My cat Yuri was never diagnosed with herpes via an eye swab test, because they have to put them under and stick a swab under their eye. Instead, the vet tried several different eye ointments with antibiotics and none really worked great, so the conclusion was that he had herpes. He did better on the ointments or gentomycin eyedrops than without them. When the last bottle of eyedrops ran out, my vet said I could also try human eye drops. Even without Lysine, Yuri does just as well or better on human Allergy Relief eye drops, one in the morning and one at night, as he did on antibiotics. A different vet did mention that it could be a blocked or deformed tear duct that made his eyes water, so who knows? But the human eye drops are working great to control his tearing.

I also switched from Iams cat food to "Before Grain". I always had to coax Yuri to eat the Iams, but now that he is on BG, he eats great and is much healthier overall. The price for BG on Amazon is about the same as Iams in the grocery store: $2/lb or so. Highly recommended.

Peanut Butter was getting sick with an upper respiratory infection every month. After taking two of these everyday he has one very minor flare up every 6-8 months. I break it up into small pieces and put it in with his hard food. For me it is worth the money.
