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).

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.

I feed a colony of feral cats, and in the past week, about 7 of them had runny eyes, runny noses and sneezing frequently. They weren't feeling well and not eating as much food as usual. I tried this and within 5 days, they are all recovering. I put a little bit in each bowl once a day. They didn't notice anything unusual about the food, since there is no smell or flavor to it. NOW, they aren't sneezing, their eyes are clearing, and they are feeling much better! This really works and they are so grateful!

I decided to try this to hopefully help my mostly feral rescue cats one leaky eye, since I can't touch him to treat it. I give him 1/16th of a tsp in his wet food once every 4 days, he's only had 5 doses and it looks like it's helping his eye already! I included a before and after pictures over the 20 days he's been on it. Looks to be a legit product, and with the dosage size it should last a long time!

I have a cat with feline herpes, and Lysine makes all the difference in her ability to breathe well. This bottle from Now Pet Health is a great value in comparison to the major competing brand I'd been using for years. It works just as well and lasts a little longer for a lower price. It's easy to measure with the tiny included scoop. Without lysine, my cat is congested. When she's congested, she doesn't eat. This is vital to her health. Both of my cats like the taste. I'm thankful to have found this product.
