Best cat lysine ever!
I have purchased quite a few different brands and forms of Lysine over the years but this one is the best. It cleared up my cat’s eye drainage and inflammation after a few days. He also liked the flavor which was a very welcome surprise. I will definitely be buying again.

Great product
I have 2 kitties that have chronic respiratory and sinus infections. L-lysine was suggested to help with their condition. We tried all the powdered forms of this supplement but being cats they would not eat it in any type of food. This product was our last resort and I honestly wish it was our first go-to product. My kitties love the taste and its so easy to administer! I personally do not use the dropper, by my own choice, as my kitties try to chew it. I now use a 1 ml luer tip syringe to measure and administer the accurate dosage. Not only do my cats look forward to medicine time but I know the product is working as their symptoms have drastically lessened over the past 2 months and they have more energy as well. Like any supplement, this takes time to work, so give it a few months. I'm glad we decided to stay the course as after 2 months my cats show marked improvement and are continuing to progress more each week. I will continue to use this product, as for my kitties, their condition will back slide and their health will once again decline if we stop. Their quality of life is very important and this has now become our daily routine and since the kitties love the taste, they will continue to eagerly consume it. Please give this product a try and use it for a while, as to give it a chance to work. Your kitties will thank you !

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.

Awesome Product!
I have become feeder of all things wild in the neighborhood. About two months ago one of the feral cats had four kittens, two have died and the other two had serious congestion and runny pus that was drying making them unable to open their eyes. Since I feed eleven cats I have treated all of them with the Santkol L-lysine on canned food, a treat regardless of the L-Lysine. In just three days, the kittens have eyes open (also using HICC eye wipes) and their noses have quit running, sneezing has slowed down considerably. Momma cat is (hopefully) about to be trapped and fixed!

Delicious supplement easy for kitty to eat
Lysine supplements were recommended by our vet for our cat to improve his immune system. This liquid form was the first one he would eagerly consume. We have been using it for the last few years and are very happy with it!

Amazing Game changer for my furbaby
Let me start with - I seldom..very seldom write reviews. I usually don't believe them. Maybe some are written because something is promised for writing one. I've been promised nothing. I'm a cat person.. I have several. So I've dealt with all that comes with them. Many get a Cat cold at some time in their life. Most often its viral and just has to run its course.. My newest addition.. Is 3mths old. He has the worst cat cold I've ever experienced. Very runny eyes, nose, and sneezing.. He was miserable. Awake nonstop. Very short naps here and there.. Short I mean maybe 4 or 5 minutes at a time. He looked like he had not slept in days. Ordered this product. Had to go to work for half a day. Product was delivered by the time I got home. He looked absolutely miserable- like he had not slept for days. Eyes and nose runny and puffy and alot of sneezing. Opened the product and mixed it with a little wet treat.. Even gave him some without being mixed. He lapped it up.. I would say within 20 minutes.. He was calm enough to lay down.. And slept for 3 hrs.. He got up after that.. Moved around.. And is sleeping again. It's not a cure. But it treats the symptoms. Huge game changer for my little guy. I recommend this to anyone with a furbaby suffering the cat cold symptoms. if your baby continues suffering - of course visit your vet.. But this stuff.. Liquid gold.. Thank you.

My cat loves the taste! Easy to administer 'medicine'.
My cat absolutely loves the taste of this product! Given to him to treat nasal congestion, coughing and sneezing. Within 24 hours and 4 doses (1 in the morning and 1 at night) he has showed marked improvement! It's very nice being able to administer 'medication' without a battle, hissing, and claws. I actually have to tell him to "slow down", lol! He pulls the dropper close in a bear hug and takes the 'meds' willingly. With that being said I do have to caution that you keep the product closed tightly and stored away from your cat as it's too tasty for them to resist! Mine acts like it's a treat! Product appears to work as stated and I am happy that my cat is on the right path to cleared sinuses and better breathing. I have not noticed any negative side effects from the use of this product. The L-Lysine arrives in a sealed amber/brown glass bottle with metered dropper. The box is insulated with an interior box. The other package is shrink wrap over cardboard. Keep the container in the original box away from excessive heat or from freezing. Think storage areas like shelf or countertop in darker corner as ideal storage areas. Package arrived in a timely manner and intact. Will recommend to fellow cat owners who have a pet suffering from nasal congestion, sneezing, etc. and will most likely be purchasing again if my cat shows signs or needing or may even order and keep on hand. So far very happy with results this product is giving! Will update if anything changes.

GREAT TASING!
my cat has chronic respiratory problems. she had a runny nose for two weeks; i took her to the vet who suggested lysine. i bought this one due to good reviews. my cat ADORES THE TASTE! she craves it! she eats it right from the dropper. I used it in conjunction with and antibiotic; ten days later she has recovered completely. I still give her the lysine on a restricted level as a preventative. i have to exercise restraint in giving it to her as she , normally picky eater, would eat it daily! i wish they could bottle 'the taste' in a treat from. it worked beautifully in conjunction w/ the antibiotic.

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.

Tolle wirksame Tropfen
Ich gebe dieses Produkt meinem Kater, der als Kitten Katzenschnupfen hatte und davon eine "Dauerrotznase" und ein trübes laufendes Auge behalten hat. Nach einem halben Jahr Eingabe ist der Schnupfen bis auf gelegentlichen Niesen weg - vor allem die "Rotzfahnen" überall, und das Auge tränt nicht mehr. Super Medikament, Dank Hähnchengeschmack kein Problem bei der Eingabe. Eins noch zum Händler: Bei der letzten Sendung war eine Flasche beschädigt - völlig problemlose Rückerstattung. Sehr empfehlenswerter Händler.
