Cats walk away from these

I actually bought this product as my vet recommended Lysine for 2 of my cats. I do have the powder, that I mix on wet food, but thought the treats would be something

I actually bought this product as my vet recommended Lysine for 2 of my cats. I do have the powder, that I mix on wet food, but thought the treats would be something added or when I don't do wet food. They sniff and walk away from these. Will not have anything to do with them. So, maybe the taste or the smell is not pleasing to them. I can't order this again...

Sounded like a good idea

I liked the idea of a lysine soft chew treat, but my picky cat was not very fond of them. I had to slice them very tiny and then he ate a few of them. But usually

I liked the idea of a lysine soft chew treat, but my picky cat was not very fond of them. I had to slice them very tiny and then he ate a few of them. But usually he just left them in the bowl. So disappointing, I thought he would love them. Might just be my cat...

No more Weepy eye on the Black cat

I have an occasional black cat that wanders through. He had a very weepy eye and this supplement worked perfectly! No more weepy eye!

Kitties love them - even if it's "medicine"

One of my kitties had cat herpes as a kitten and had quite a bit of goopy eye, and the vet recommended these as a daily supplement. She loves these! When we added

One of my kitties had cat herpes as a kitten and had quite a bit of goopy eye, and the vet recommended these as a daily supplement. She loves these! When we added a new cat to the house, we also gave it to her (because you have to be fair) and she gobbles it up. They both love the flavor. I do break it up into smaller bite-sized pieces as the large piece is probably too large for them to consume in one bite.

Great

Very hard to find Lysine that my cats will actually take. They run to me and beg for these treats, and they significantly help my cats. Didn't realize Chewy had

Feline herpes support

Helps prevent herpes flares in my cat. He thinks they're delicious. Makes a big difference in frequency of goopy eyes and sneezing fits.

They LOVED them!!!

They both wanted another one, Truffle even pawed at the bag. Now every time they hear a bag they show up out of nowhere.
