Perfect for my sneezing kitty
My adult boy tuxedo was sneezing for months, and it was just getting worse. I tried the Licks gel product and it had zero effect. This, however, I gave him 3 treats for 5 days, then 2 treats for 4 to 5 days, and his symptoms are nowhere near as bad as they were. He no longer sounds congested, he barely sneezes anymore, and he just looks so happy/content. I give him one treat every day now and he looks extremely comfortable. He loves them! But they're kind of big, so I break them up to three to four pieces so he can eat them easily. I follow it up with a catnip treat, and he loves both.

Pet's Lysine Chiken Flavor
Personally, I think it looks and smells appealing. However, my cat does not share my viewpoint. She likes crunchy stuff and these are soft, so I must let them dry out for a couple weeks before she will consider eating them, usually reluctantly.

My cat Loves 'em
As long as my cat continues to enjoy these, I will continue to purchase them. (He doesn't need to know that they are actually GOOD for him!) LOL!

Preferred Brand
I have tried many other brands of Lysine with my 2 cats, however, GNC chicken flavor is the only brand they will eat. It helps keep respiratory clear and minimizes eye discharge.

Cat will not eat!
I have a cat who need to take Lysine daily, so i ordered this thinking it would be easier, but unfortunately he will not make any attempt to eat them. I have 3 other cats, all of them also refuses to eat the Lysine treats and NONE of them are skinny or picky eaters. Very disappointed by this product.

It helps!
One of my cats has a runny eye, which my vet says is caused by the herpes virus. And when she feels stressed it gets worse. Our vet said to give her L-lysine and we found these chews as an alternative to trying to get her to lick a gel off our finger. So we give her one in the morning and evening and it really helps to control the runniness. Sometimes her eye does not run at all! Good product!!

My KItties Think these are treats!
L-Lysine seems to really help my orange tabby kitties with their immune system. I've bought another brand in the store but they are expensive. GNC's product is greater & c.heaper

Well received by our feline connaisseurs
Lysine was recommended by our vet as a preventative and both our cats enjoy eating them... a lot. The fact that they are fish-shaped but chicken-flavored does not detract from their enjoyment. Ordering them online at GNC is much, much cheaper than buying them retail at Petsmart.

Seems to work
I have four cats and two of them seemed to be coughing so I asked my vet about it and she suggested that I try the L-lysine. It seems to work for them.
