My cat has a very bad sneeze and cough. Will this help her?
Answer by ChewyNov 24, 2017
These chews support respiratory, healthy tissue, ocular functions and could work for your feline with a sneeze and cough.

are these crunchy
Answer by ChewyFeb 14, 2021
These chews are soft and chewy.

Is the chicken liver flavor from real chicken? My cat has allergy to chicken.
Answer by ChewyAug 31, 2018
The chews are made using chicken that has been hydrolyzed or broken down into its component amino acids. This makes the chews safe to feed for cats with chicken allergies.

I see a review the cat parent very upset that Vermont is using Products from China I hope No I check all the time is Vermont Products made in USA or Canada
Answer by ChewyDec 13, 2020

Pet Naturals L-Lysine

I've purchased this brand well over 5 yrs. Used to be great. Cat loved it. Had molasses smell. Now this "chicken liver" flavor smells nasty and my cat won't eat no matter what I tried. I won't force him, because maybe there is something wrong with their manufacturing or ingredients now. Very disappointing. Wish I could leave zero stars.

My kitty, who’s not especially picky, wouldn’t eat these. However, the size was good and they were chewy as promised.

Not so tasty

Does the product work? I'll never know because my cats RUN when I open the bag. I'll be looking around for another Lysine product. May I have a refund?

So my cats loved these before and would attack the bag so excited. Now I have to crush it up and mix it into their canned food. If they go back to likin em then I would recommend If they keep needin to be tricked into eatin em then I don't recommend.

My cats wouldn't eat

They are hard chews. I crushed and mixed with food and my cat who eats anything would not eat it. He ate around it. Not sure if it was because it was hard pebbles in his wet food or he didn't like the flavor. I'll try the type you sprinkle on next.

Picky cat

Picky cat won't touch them. They do have a weird, strong smell. I'll have to find some other means of giving him Lysine.

My cat won't touch these so I gave them to a friend of mine. Her cat won't touch them either. Total waste of money.

Something has changed

My cat usually love these treats. For the last month I would say he stopped eating them and I didn't know if it's cuz I was breaking them up too small but they also felt dried out and I thought that was because it was my apartment. I bought a new bag and immediately opened one up he still did not want them in felt dry right out of the package. Too hard type of dry. I did go back to just breaking them in half and not smaller and he did them or at least 1/2 but only for one day. Not sure why they seem like they're harder than a rock.
