This works
This really worked on one of my cat who had continuous sneezing, and my cats did not have an issue with the taste

We're really happy with this. My cat has had on and off problems with his eyes for years. Despite all efforts he kept getting problems. Since giving him this product with his food ( took him a couple of feeds to get used to it ) he's not had a problem for a long time now and seems happy and healthy

GREAT!! Having tried other brands, this is my number #1 choice when I have sick, feral cats in my colonies. I feed close to 27, TNR'd cats in multiple locations & when they show up w weepy eyes, sneezing &/or signs of upper respiratory distress, I mix this in w wet food, adding a little warm water. The results have been amazing! Usually, I see results after the 2nd feeding. I just had a very sick male, I think he may have FIV but a URI was hitting him hard, he had stopped eating because he couldn't smell through the nose congestion.. I used sardines mixed w canned, tuna cat food & a little warm water w this Lysine mixed in.. he was in bad shape but the smell was enough to trigger him to eat & by day 3, he was remarkably improved, he's almost back to himself again. -- For feral colonies, this is perfect to help their immune systems! Not much is used each time so it lasts a while, a good value for the price. -- I use it regularly now for all the outdoor cats, I do recommend adding it to wet food w a little water so it dissolves. Trust me, this stuff is great for URI & weepy eye issues!

Seems to work well for weepy eyes (but doesn't get rid of it entirely), I mix it with wet food and my boy doesn't seem to notice the taste. Easy to use with the scoop.

We have a three cat household, and it's important to us that all three cats stay healthy. Lysine is a good supplement to support immune function in felines, and all three of our roommates get a good slosh of this stuff with every meal. NOne of them have ever balked at the taste or texture, and they gobble up all their food. They've stayed healthy and feisty and very much themselves, and what could be better? Check with your vet, but lysine has been very good for our household.

My first bottle is almost finished so I was browsing here to see if I should purchase a second bottle. When I read the reviews I realised kitten has not sneezed or had runny eyes for a long time now. I think I have fed him this product for a few months. He is healthy and has a good appetite so then it must the working!
