Has vastly improved my housecat's drippy nose and sneezing
Having spent 2K on seeing 5 vets over four months, this appears to have massively reduced my cat's drippy nose and sneezing and she can now obviously smell more, and as a result, is less of a fussy eater. The vets reached the point where they could offer no more help, other than perhaps a referral for a CT scan, etc. but as my cat was basically otherwise well, and she chooses to remain indoors, this felt unnecessary. We did agree to an anaesthetic and nasal camera, which reassured us that polyps/growths appear unlikely, so before going down that route, I would thoroughly recommend giving this a try. Within 5 days of just a teeny amount in her food, once a day, there was a massive improvement.

Hopefully helping cat`s immunity
I`ve given it 4 stars as I haven`t been using it very long, so don`t know how effective it will be. My cat has had 2 bouts of runny nose/sneezing (expensive vet visits) He hasn`t had another flare up while I`ve been using this, so will have to wait and see if it reduces his symptoms/length of flare up. He happily eats it mixed in with Lick - e - Lix, and there isn`t any strong smell to put him off

This helps!
I know Now is a good brand but never try, turned out it helps with my cat’s eye issue very effective. I used this for around 3 weeks, can see the obvious different. If Now can include a tiny spoon with exact measurement would be a bonus, 1/16 teaspoon is hard to measure 😅

Good for reducing cat flu symptoms
Our cat was struggling with cat flu and so we took her to the vet. A two week course of antibiotics was prescribed, but by the end of the two weeks she was still clearly struggling - sneezing, dribbling, mouth ulcers, overcleaning front and back paws, and conjunctivitis. She was in considerable stress and I didn't think she would survive. Out of desperation, I checked many on-line reviews of this product, and they were mostly very positive, so I purchased a jar of the l-lysin. Our cat's health has improved immensely and she's pretty much back to her normal happy self with bags of energy. I use the product now every day for all four of my cats - just a very light sprinkling on their wet food, and they still eat it. So, I would definitely recommend this product.

Wasted on my two cats
My both cats are dry food eaters, so I thought the powder form of lysine would be a good choice for them. However, this particular lysine is more small-granular in consistency(think Vanish powder). It went to the bottom of the dish hardly sticking to oils on the dry food surface. I had to blend it to make into fine powder to make it stick. Unfortunately, both cats keep refusing to eat food with a dose of powder sprinkled onto it, even when mixed in and invisible to the eye. They seem to taste it and after a couple of bites refuse to continue eating. Looks like a wasted investment into their wellbeing.

Worked well
This product definitely helped my cat's sneezing / watery eyes but I was using it daily at a vet's recommendation.

Really improved my cat's life
I almost never write product reviews, especially on Amazon. So this is a testament to how well this stuff works. I have an exotic shorthair. Flat face, goopey eyes even on the best of days, trouble breathing, etc. My cat also seems to have almost no sense of smell probably because she has tiny nostrils and respiratory issues - this means she eats only one type of particularly pungent kibble, no interest in any of the 20+ different treat brands I've got her, no interest in wet food, no interest in any human food. I do not agree with the breed, she was a rescue and really is the sweetest cat ever. Her life has been difficult because of her breed specific issues. I've had her on this for around 2 weeks and the difference is astounding. I haven't had to wipe her face at all this week, very little goops (nothing she can't groom off herself), her breathing is way better, and she is taking an interest in other food and sniffing EVERYTHING. I'm shocked. I assumed this would help a bit but she really seems so much more lively and happy. She's acting like an actual cat, playing and running around (which would have tired her out way quicker before), doing cat things she hasn't done before. I've had her for 2 years and I've never seen her like this. YMMV of course, and I can't tell if the results will last long term. But I am very satisfied with this purchase. Also great value. No scoop is included but it's only a 1/8 tsp twice a week sprinkled over her food. This will last easily a year+. She hasn't turned her nose up at it yet so I don't think she notices it's there. Definitely worth a try. Especially if you have a brachycephalic cat breed (flat face).

Cleared Up Goopy Eyes and Runny Nose in a Week
I bought this last year for a friend with a cat that had herpes, but she didn't want it. Recently, I took in a wounded feral cat that had been attacked by another animal. He had goopy eyes and a runny nose. I consulted the vet who treated the cat's abscess about using L-Lysine to try to clear up his eyes and nose, and the vet agreed it was worth a try and figured out the correct dosage for the cat. I have been mixing it into his wet food for a week now, and his eyes and nose have cleared up. I am posting a before and after picture of this tangerine dream of a cat. He's semi-feral and will not let me clean his eyes, but they are so much better now. The powder seems to dissolve into the wet food because he eats the wet food without any issues, so I am assuming that it's not altering the flavor of the wet food. He now looks better than ever.
