Picky cat won't touch it

I have a super picky cat who hates anything fish flavored. I failed to notice that the flavor is chicken AND fish before I bought this. As much as I tried to mask it in her food, she won't touch it. My other cats love it, but they're not the ones who need it. I wish they had more flavor options, like just chicken flavored. Based on the amazing reviews, I was really hoping this could work for her :(

Leia's Herpes Support

My 1 year old cat Leia was rescued at 4 months with herpes or some other STD that gives her a goopy eye, if left untreated. I'm hoping that this supplement will help prevent her symptoms. Stay tuned!

Healthy cat MAGIC!

My cat has had “weepy eyes” since she was a kitten, and nothing the Vet prescribed worked. This simple amino acid DOES work like magic, and she loves it! I use 1/4th of a tiny scoop once a day and her eyes are clear. It’s also kept her healthy and energized. I highly recommend it.

great find

My vet recommended that I use a supplement with l-lysine due to my cats predisposition to respiratory infections. I have tried chews and pastes in the past but my cat would not eat them. This was easy to sprinkle in with her food. She has not seemed to mind the taste which is good. Would recommend.

Cat colds, upper respiratory

My cats all had, watery, gunky, eyes with slight traves of pink, (blood) sneezes, they were miserable, used vet prescription eye drops, that did not help at all. I have my cats this supplement twice, so far and they are almost 100% clear. After the first dose, their eyes were clear, so Overnight! Not saying don't take your cat to the vet, bit I know this respiratory cold, I e dealt with it before, and it was way harder to rest with anti biotics and all that, I'm so impressed with this product.

Tomlyn immune support

I’m giving this to an old cat who was diagnosed with FL . It’s helping him I think. His eyes and nose look much better.

This product has turned my cats health around!

My cat is getting older and has had a leaky eye and been prone to sinus issues her whole life. I noticed she was starting to seem lethargic and wasn't really eating as well as sneezing quite a bit. After a few days of adding this to her wet food she seems 5 years younger! shes zooming around at night again, vocal, affectionate, eating regularly, and no more sneezing! Also her coat is so fluffy and healthy looking. I'm so happy to see her happy again, highly reccommend this product! :)

Accepted by Cat

My very ill rescued kitty is readily eating this twice daily (mixed with food). We're building strength for an upcoming surgery. He is either hesitant to consume or rejects his other meds, so the ease of administering this med makes life easier for both of us. We don't have a bloodwork update yet to confirm that the med is working, but he is acting more energetic. I have used and trust other products from the Tomlyn brand.
