Rated 4.1 out of 5 by 140 reviewers.
Rated 1 out of 5 by 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. January 13, 2017
Rated 2 out of 5 by Cat didn't really like it My kitten didn't really like these as they were very hard and too large for her to eat in one bite. I have been giving her the Viralys oral gel everyday, and was hoping that these would be an easier substitute for that, but nope-- I'll stick to the gel. January 12, 2017
Rated 5 out of 5 by 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! January 11, 2017
Rated 1 out of 5 by VERY hard product Kitties tried to eat, but even broken up they walked away. Hope other kitties will benefit. January 7, 2017
Rated 1 out of 5 by 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 :( January 7, 2017
Rated 2 out of 5 by 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. December 30, 2016
Rated 1 out of 5 by Cats wouldn't touch this. Got 21 cats.. They all smelled it than just walked away.. December 25, 2016
Rated 2 out of 5 by Anything but chewable! After reading such rave reviews about the benefits of lysine, I decided to give these chews a try. Five of my seven cats were struggling with an upper respiratory infection, so I thought it was a good time to implement this essential nutrient into their diet. I was very disappointed when I opened the package and handled one of the so-called-chewables. There is no way I was going to give these to the cats since they are not soft and certainly not chewable. They are like stale gummies. Rather than waste the product, I used my thumb nail to scrape off small particles that I then mixed in with their food. Only two of the cats would eat their food. Our vet gave us lysine gel in a pump, so I tried it. One cat loves the gel and will lick it off my finger, and a few others will eat it if it's mixed in with a smelly food like tuna. If I can't give the bag of chews away, they will be thrown out, but I am going to keep trying to incorporate the lysine gel into my cats' diet. February 2, 2016
