The cats are addicted to it, and it's helping with FHV symptoms!
Cats love the flavor and we have no issues with them refusing it. It seems to be helping with the kittens that have FHV and the eye drainage, sneezing has gotten better. Wish the dropper were better. It does not fill to the top line, only halfway, which is not a big deal but it doubles the time it takes when giving to a large amount of cats. That's the only drawback. I'll still be ordering more of this soon though, good product!

Works great for my FIV+ Rescue Cat
We rescued a stray cat approximately 9-mo ago that was living on our property (long before we moved in). When we took him in he was extremely frail and emaciated, with very little energy, and he was runny, sneezy and wheezy. SHORT STORY (if you just want to get to the point): We’ve recently begun using this L-Lysine product and it’s definitely helping (along with daily Albuterol nebulizer treatments). I definitely recommend it. He also enjoys the flavor (thank goodness). The only negative is that it can get messy, as it drips off the glass dropper - so - bring a paper towel with you! LONG STORY (if you’re curious): For context, when we moved into our temporary rental while buying a home 13-mo ago there were approximately 15 stray cats on the Lot and we installed gravity feeders, automatic water bowls, and temperature controlled cat houses on the side of the home for them. They were all VERY friendly and took to us quickly, even responding to the names we gave them, over time. We worked with a local nonprofit to get them TNR’d, as well as their much needed vaccines. For the most part, they were just hungry. But they gained weight quickly once they started being fed regularly and had a safe/comfortable place to eat and sleep. Anyway, back to the one we took in… he was NOT gaining weight and his energy was fading, fast. One night we came home from a dinner out and noticed that he couldn’t walk across the driveway to say hi to us, which meant he was likely not walking to the food/water, either. When I went to his self-proclaimed sleeping spot he was purring loudly and rubbing his head in my hands, but it was obvious that he was giving me every ounce of energy he had. His breathing was labored, and nose running profusely. He was one of the few cats that already had an “ear tip” (meaning he was TNR’d before we became involved), which meant the nonprofit wouldn’t typically get involved, but luckily we are good friends with the woman who runs it so we immediately called her (at 9 p.m., as they do their nonprofit TNR’s at a local shelter through the night when the facility is closed) and she told us to bring him right away. We put him in the carrier, which he didn’t even protest to, and drove him over and left him there for the night. Their vet was able to determine that he had a SEVERE URI (Upper Respiratory Infection), and was SEVERELY DEHYDRATED (he went through 3x the amount of fluids a typical stray would receive). We also opted for the SNAP Test and were told that he DOES, in fact, have FIV. They gave him a heftily dosed antibiotic shot and let us take him home the following morning. There was NO WAY I was putting him back outside in that state. We quarantined him inside our home (we had 3 of our own personal indoor cats and URI’s are extremely contagious), and for 3-WEEKS he barely wanted to leave his sleep space. He slept like he had never had a true peaceful moment of sleep in his life! He was so grateful and loving. He also doubled his weight in that short period of time. We realized almost immediately that he was now a part of the family. Unfortunately, the URI didn’t seem to fully clear so the vet gave him an oral round of antibiotics. He got “better” but within days of finishing the prescription his running nose, sneezing, runny eyes and asthma attacks would return. Fast forward to 9-mo later and he has (unfortunately) been through 5 rounds of different antibiotics. All had the same result: good then back to sick almost immediately. He’s also been to the vet (not the nonprofit) 4 times, which is pricey (but worth it for his comfort). We’re now waiting on the lab test to come back on his nasal swab - as they have been treating him as bacterial, but, given that he is FIV+, it’s likely viral. Anti-virals are expensive and since we did the SNAP test without proper education prior to attaining pet insurance, it’s considered a “pre-existing condition” so it’s not covered. In the interim, we’ve recently begun using this L-Lysine product and it’s definitely helping (along with daily Albuterol nebulizer treatments). I definitely recommend it. It helps to keep the runny, sneezy, wheezy stuff at bay. If it has been working well for him, it should certainly help others, too. The product is more like a broth, than a syrup, and it is made with quality ingredients.

My cat's like it. It's good
Only used gels before with mixed results on whether my cat's would eat it or not, but they apparently loved this flavor with their food & cleared up the runny eyes & congestion pretty quickly! It's good. They like it. I like it.

Miraculously effective!
Is it a miracle? Time will tell but after less than 24 hours, my British Shorthair who has had runny eyes for nearly 9 years is sitting in the window right now with dry eyes 🤯. He also recently, over the last 2 years, starting sneezing during springtime. I didn’t know cats get allergies, but putting two and two together, it must be that. Anyway, I have not heard one sneeze from him since I gave him his first dose. He’s a big boy (18lb) so I gave him 2 droppers full in his wet food. He’s picky, he would not lick it up directly from the dropper. I will update this review if anything changes but for now, I am completely astonished at how effective this supplement is. In fact, I feel bad I didn’t do this sooner. We’ll see if his coat improves and/or his energy. So far, great product and I highly recommend giving it a shot to treat leaky eyes. Photos are before and today!!

It's literally like video
My one cat cat licks the dropper or loves it on his food. He has found his new favorite treat.. now my other cat, she is not a fan of anything medicine. I'll update this with a video of 1 vs the other. We've tried mixing it with her food and she's still like, "I can't go for that, no can do." Effective, smells like chicken great price, the quantity/size is decent. It's not chunky it's smooth. Safe

Persian miracle drops!
This product has been a game changer for my Persian. Before she would wake up with her eyes, crusted shut and be wheezy all day long. One dropper of this every night has totally cleared her up! No more goopy eyes, they are totally clear 24 seven. We still get an occasional sneeze/wheeze but that’s true of any cat. I cannot tell you the difference this has made. And Mabel loves the flavor of this! She would drink the entire bottle if I left it out! Please give it a try I think you’ll will be pleased. It has made our Persian’s life so much more comfortable. The first picture is after having used the drops for a couple of weeks and the second picture is before. You can see how she can hardly get her eyelids open. But after her eyes are as clear as can be.

Funziona davvero
Ho trovato un valido alleato dopo tanti prodotti provati. Il mio gatto soffre di calicivirosi dalla nascita, questo comporta un sistema immunitario debole che nel suo caso si manifesta con frequenti raffreddori ma soprattutto gengiviti e ulcere nella bocca che gli provocano forti dolori e spesso rinuncia a mangiare. Da quando sta assumendo questo prodotto è cambiato moltissimo, mangia con appetitto non si lamenta più mentre mastica( cosa che prima avveniva costantemente con violenti scatti ) non lacrima non tossisce e non gli cola il naso! Si vede a occhio che sta bene ed è molto piu attivo,mentre prima era spesso letargico. Lo consiglio a tutti. Provare per credere.

Works for seasonal allergies
These drops are amazing. My cat suffers with seasonal allergies in the summer and it really affects his mood, he used to get gunky eyes etc. Using L - Lysine fixed all these, I can have windows open all day and all night, it doesn't affect him anymore. He is a very fussy eater but he's obsessed with the flavour. He begs for these every morning. Only downside is that due to his size, bottle only lasts a month so works out pretty expensive.

muy buena elección 👌
Mucho mejor que la L-lisina en polvo, los michis lo toleran más y mejor🥰 les estoy dando otras cosas de complemento,pero creo que funciona muy bien, sobretodo para los gatos con gengivitis,un complemento efectivo...pero es mucho más costosa que el bote en polvo y rinde menos por supuesto, aunque repito se la toman mejor en con su comida húmeda
