Kitty likes these
Lysine has always helped our kitty with her runny nose and eyes. Glad to have in a chew to make it easy instead of adding to her food.

Whose mistake, yours in producing , or mine in ordering ?!
Too many "surprise" ingredients. I wanted a food that was just a wholesome "carrier" for the L-Lysine , not something that Vetriscience went crazy over for their product enhancement employees to produce. Never again will I stray from my original order(s) for my cat !

Kitty health
Once I understood the "visual" packaging change, I found my product quickly; just disappointed there is no longer the 120 count of this product for my 4 cats. I stand with this product.

Unfortunately, not one of my 4 cats would not eat these
Not one of my 4 cats would eat this lysine treat. I bought 2 bags and was hopeful this would be a good option for my cats. I tried several times and even opened the 2nd bag and tried them as well but no one would eat them. They arrived all clumped together, almost like they got hot in transit, though the weather was cold out. My cats are generally pigs and eat anything but the palatabilty was not here for us sadly.

Arrived crunchy and small cat can't chew them.
When I tried to break off a small piece, it crumbled. I had understood that the texture would be chewy. I'd like to return/exchange the item if you cannot send me chewable suitable for an 8 1/2 pound cat.

Cat didn't like these
Well, I had hoped to give this a solid try, but after numerous days of offering this and my cat rejecting, I can only say my cat didn't like the taste.

Cats wont eat them
Purchased on advice from a vet friend to help 4 cats after a long distance move - 1 cat ate one but no more, the other 3 wont touch them. These cats aren't spoilt, they are barn cats. Very disappointed

Hard crumbling that none of 5 cats will eat
I knew when the package was as hard as a rock there was something wrong. I have 5 cats who all loved them in the past. Not one of them will eat this pack. Will be stopping my subscription to them. 548020001 0425

Seems to be helping boost our cat's immune system as he recovers from recent illness. His appearance has improved greatly since we added these to his diet!

VetriScience Lysine is great!
I have an outdoor kitty that I feed on my porch. Last winter, he developed a really bad congestion in his nose that he was unable to eat when he bent his head over his food dish. He sneezed frequently, but nothing seemed to come out. My vet recommended the Lysine Plus because she said leaf pollen was very bad. I put it on his food, and within three days, he was clear. Since it boosts cats' immunity, I continue to give this to him daily. He never has runny eyes, nor does he sneeze any more.
