My cats love it!
This product works well! My two cats enjoy the taste when I put it on their wet food. My cat deals with shedding and dandruff, but I feel her healthy routine combined with the Oral Paste is helping. The cats doing well certainly reduces all the vet appointments.

Worth trying!
I do feel like this helped my cat who was having a flare up of sorts. He was sneezing, watery eyes, hot ears. We mixed this with some churu food and it perked him up within 24 hours. My other cat wouldn’t eat it so we did the trick where you put some on his paw and he has to lick it off and he ate it just fine and it helped his symptoms too. Definitely recommend.

Great great product for Upper Respiratory Infection
I ordered this late in the evening last night and received it late morning, thanks Amazon prime. My 17 year old cat got an upper respiratory infection. It started out as just sneezing but last night stopped eating and drinking watering eyes. Vet was closed so I read all the reviews for other supplements offered. This was the most expensive but bigger in size for gels or paste. Booboo does not eat wet food or treats so I needed this kind. Gave it to him as soon as I received it. Pump worked perfect and I put it just under his nose. He licked it up right away. I thought the smell was bad, but I wasn't eating it. Second pump put in his mouth no problem. Well by 4 pm today he got up and ate/drank and was not sneezing constantly. Gave him his night doses at 8:30pm. He only sneezed twice, no tearing and is out off my bed and cuddling by me. Will keep giving him a the week to make sure he is totally ok. This saved me a trip to emergency vet and from other reviews is cheaper here than from the vets office who recommended this to others. Great product and thank you for getting my geriatric kitty back to health in one day. Sorry for the length but wanted people to know how great this worked for Booboo as URI is serious when they stop eating and drinking and they r so stuffed up. All clear now yeah. Update:. I gave the paste to him for 5 days to make sure the URI was totally gone. He was asymptomatic after 3.5 days. Hasn't had a reoccurrence since and not one sneeze or eye watering either. Still have lots just in case.

Seemed to work
I had a 7 month old kitten with a URI and I didn’t want my 7 year old cat to catch it. I put both on this - used it once a day instead of twice - they didn’t like the taste so I had to mix it with their wet food. I’d say within about a week and half, the sneezing improved and my older cat never did come down with a full case of it. Just mild with occasional sneezing. They are both 100% better now. I would consider it effective and cost wise, less that a vet visit.

Recommended by Vet- worked amazingly!
My 15 yr old cat began to get matter in his eyes and the vet thought it might be a clogged tear duct. They recommended this product. It is amazing it worked so well... and quickly. One squirt in the am and one in the pm in a soft treat and that's all there is to it.

This works
If your kitty has upper respiratory infection this will help them get over it. Easiest to add to their food. Give one pump daily. Can even give daily to prevent a developing respiratory infection. It is an amino acid they get in meat,but blocks the virus.

Not so tasty for my cats
The seller was great - quickly shipped, nice packaging. I would not hesitate to do business again. As far as the product goes...health benefits seem to be there, but the issue is that none of my cats, including the one for whom this is intended, will eat this without mixing it with something else. And even then, it takes some heavy encouragement. Supposedly "tuna" flavor. I have to mix this with some of the "squeezable" stuff that all our cats love in order to get the cat that needs it to reluctantly eat it. I just think it should be tastier somehow. The instructions say that you could even wipe it on the cat, like their paws, to get them to lick it off. Well, trying that resulted in some antics that should have been recorded for TikTok or YT.

I have been using this product for years now for my cats. They love the taste! It supports respiratory health and maintains normal eye function. I give it to all my cats when they have these problems and I'm happy with the result. It enhances their immune system too! Great product!

My very fussy cat eats it in her food no problem, and her weepy eyes (which is what the vet recommended it for) have improved greatly

I have long heard about lysine to prevent cold sores and this feline version certainly does the job for our lovely cat who suffers from FIV and gets the occasional sore/ulcer.
