Pet Naturals of Vermont L-Lysine Cat Chews is rated 4.1 out of 5 by 143.
Rated 3 out of 5 by from A little tough but the cat likes them. The chews seem to be a little tough for my 14 and a half year old cat, but he seems to enjoy them. I have started breaking them up into smaller pieces and that has apparently solved the toughness issue. Plus he thinks he's getting more. The quality and effectiveness of the vitamin is encouraging. The last couple of winter he's developed a slight runny nose. He was on a gel that had to be given to him orally via a syringe and he hated that. The chews are a nice alternative, and his sniffles have subsided.

Rated 4 out of 5 by from My Cat Loves Them! My vet recommended L-Lysine for my 14 year old Maine Coon mix. He had developed bronchitis, and spent almost two weeks in and out of the animal hospital getting nebulizer treatments. He now gets L-Lysine daily, and rarely coughs at all! I do wish that this product did not have artificial preservatives, that's why I gave it four stars.

Rated 1 out of 5 by from Too hard for to chew! I bought this product but my cat won't eat them. They are too hard for his teeth.I thought it was just his age but my younger cat had a hard time, too. Will not buy these. Throwing the bag away :(

Rated 1 out of 5 by from Too hard, cats wouldnt eat I wanted to try this as apposed to buying my normal brand and to no avail none of them wanted anything to do with it, I tried breaking it into little pieces and they still wanted nothing to do with it. I've 8 cats who need to have lysine for their immune system and their respiratory system, these chews are too hard and dry even though I tried to wet them the cats wanted nothing to do with it. So, NO I will not recommend this product. I'll be going back to the brand they like to keep them healthy.

Rated 5 out of 5 by from Love it! All of my cats love these! My two strays that have recently adopted me love them and I've seen an improvement in their eyes and my littlegirl cat has a scratched cornea and afilm develops over it which has been less noticeable and her eye has been a lot less runny. I would recommend these as they are a lot easier to administer and kitty approved!

Rated 5 out of 5 by from They Love Them!! Two cats both have URIs. They come running when I shake the bag. Have not purchased from Chewy yet - just signed on to price check. Bought two bags locally for $10 each today. Will be purchasing here for much less next time!

Rated 4 out of 5 by from Easy to administer I purchased these chews secondly to some I got at Petsmart which were not accepted by the cat I wanted mostly to take them. She likes the Vermont Lysine, and takes two a day to help with viral infections.

Rated 2 out of 5 by from Not the best My cats are older so this product was not usable. Too hard so I had to break it up into tiny pieces. Not my fav thing to do.
