Solves Common Feline Wellness Concerns
Cats cannot produce enough L-Lysine on their own, yet this essential amino acid is critical for immune and respiratory health. Without sufficient lysine, many cats face recurring discomforts like sneezing, watery eyes, nasal discharge, and seasonal or stress-related immune dips. Our paste is specially formulated to target these issues at the source, helping your cat stay comfortable and resilient year-round.

Multi-Benefit Support for Total Cat Wellness
Our premium L-Lysine paste delivers full-body care with every serving: 500mg of pure L-Lysine HCl per serving soothes common discomforts, while Astragalus, Codonopsis, and Atractylodes strengthen immune response; Taurine, B Vitamins (B1, B3, B7), and natural botanicals boost energy levels and support faster recovery from stress or seasonal challenges; Burdock Seed, Omega-3 fatty acids, and Vitamin E nourish healthy skin and coat, while gentle herbs support balanced digestion for cats of all ages.

Palatable Flavor & Easy Feeding
Made with real chicken powder and whole goat milk for a rich, irresistible taste, our smooth paste appeals to even the pickiest eaters. It eliminates the hassle of messy powders, hard pills, or unpalatable supplements: simply feed directly from the tube, mix with food, or apply on your cat’s paw for easy self-licking. The grain-free, alcohol-free, gluten-free formula with no additives is completely safe for kittens, adults, and senior cats of all breeds and sizes.

Designed for daily use for cats of all ages, from kittens to senior cats. Follow the label directions for the appropriate daily serving amount.

Feed directly from the tube, mix with food, or apply to the paw for self-licking. The paste format offers a simple way to add daily L-Lysine support without pills, powders, or forced dosing.

Made with L-Lysine, taurine, omega-3 fatty acids, vitamin E, B vitamins, and supportive herbs including astragalus, codonopsis, atractylodes, and burdock seed. This formula is designed to help support immune health, respiratory wellness, skin and coat health, digestion, and everyday feline vitality.

Easy to Give, Tasty, and Great Immune Support for Cats!

The Santkol L-Lysine paste has been a great addition to my cat's daily routine. It's designed to support immune health, normal eye function, and respiratory wellness, which is especially helpful for indoor cats or cats prone to sniffles and watery eyes.
I really like that this formula includes taurine, omega-3s, and added vitamins, so it feels like more than just a basic lysine supplement. The chicken flavor is a big win my cat accepts it easily, either directly or mixed into food, with no fuss.
The paste texture makes dosing simple and mess-free, and the 60ml tube lasts a decent amount of time with regular use.
? Pros:
? Supports immune system, eyes, and respiratory health
? Includes taurine, omega-3, and vitamins
? Chicken flavor cats enjoy
? Easy-to-use paste format

? Great for daily maintenance or immune support
? Suitable for adult cats and kittens (as directed)
? Cons:
? Benefits build gradually with consistent use
? Tube may go fast in multi-cat households
Bottom line:
A well-rounded lysine supplement that's easy to give and supports multiple aspects of cat health. If your cat needs immune or respiratory support, this is a solid, cat-approved choice.

A Picky cat and non picky cat and both liked the flavor

I have a Picky cat and non picky cat and both liked the flavor of this and I would put it on a dish and they licked it off. I love giving Lysine to my cats for their health so I will be buying more of this.

So pleased that my cats actually like this paste.

I have a colony of feral.cats that we adopted from around the property we moved to about 12 years ago.

They all.live with us full-time as our house cats now and we do the very best we can to make up for what their lives used to be like.

Unfortunately, the kittens (now 10 years old) that were born into the colony were all born with an upper respiratory virus that did some.permanent damage to some of them before we could get our hands on them.

With the help.of our veterinarian and a lot of trial and error we've managed to use lysine supplementation to keep that virus in check. The biggest difficulty with that has been finding ways to get the lysine into their systems. This is one o the first products we haven't had to hide in something else to get them to take it. That is a blessing g because it makes it much easier to kniw exactly how much is being ingested so we can know for sure they're getting the therapeutic dose needed.

It doesn't smell offensive to me but the cats can certainly smell it.

The cats eat it like a treat. They are that pleased with the taste. Can we take a.minute to praise a supply that eats like a treat?!?!

It seems to be as effective as any of their other lysine supplements as we've had no flares and no sniffles when using it.

Our vet approves of the product though did ask us to not give other supplements on days when we use it since it it a combination product.

We'll definitely be keeping this in our arsenal and would recommend to others using the same.

Thanks for a great product at a reasonable price.

Vet said my cat was really doing well. He was close to not making it, but now he's energetic and very playful.

Purrfect L-Lysine Supplement!

"What a great idea!" Says Delaney. This 'cat paste' as I'm now calling it is approved by my chunky monkey! I didn't get a video of my stray I care for eating it on top of her food, but from Laney's perspective you get the point. Both cats I gave this to two days in a row now loved it!
?
The ingredients are all great, so if this supplemental paste provides what it says it does, I will absolutely be purchasing this from here on out instead of all the vitamins/supplements separately that I do for my cats. (I also have 3 strictly indoor male cats that I will additionally be trying to give this to as well but 2 of them are super picky with 'wet food' period.)
?
The measuring apparatus is super simple to use to get the correct dosage per weight of your cat. It was difficult for me to do one-handed while trying to take a video of dispensing it to my cat, but you get the point. It was even easier to squeeze out on top of wet food to give to the second, but it is so tasty that my cali girl (who is in our garden shed for the winter) ate it right off the tip of the nozzle!
?
For this reason, especially because I've gone all sorts of roundabout ways of getting L-Lysine and other vitamins into all cats I've ever taken care of [personal or rescue] I will strongly be considering purchasing a couple of these dispensers to keep on hand at a time for the price that a single one comes at.

Tasty!

What good are vitamins if they don't taste great? There is no worries for this as my three cats lick this up before they eat. I wish I had this product earlier: 2/3 of my indoor cats had a cat cold. Sneezing, running nose, laying around. It's my understanding that lysine is good for the immune system so I'm keeping some for the next virus (?) the cats have. It would be nice to avoid to a vet. There is two years left on the expiration. Easy to measure dosage on the tube without dirtying a measurement spoon. Good value for the money, especially compared to a vet visit. The product must be good as it's a human-grade paste (no, I didn't try it, ha)!

Smells Fishy, but My Cats Approve

ARFUNY L-Lysine for cats is super easy to dose for my cats.
The smell is more like anchovy than chicken, but surprisingly my cat was very attracted to it and had no problem eating it. My other cat is shy but still showed some interest.
So far it seems like a good product, and I'm happy with how well they're taking it.

Cat Approved

When I saw this I felt like it would be handy to have for my outdoor cat. She is a farm cat and she absolutely loves being outside. She is very healthy but sometimes in the winter her meow is a bit horse and it seems like she has a cat cold.

L-lysine is an essential amino acid supplement for cats, primarily used to support immune health and manage symptoms of the common Feline Herpesvirus (FHV-1), like sneezing and watery eyes.

It is easy to extrude the proper dose out onto her food and she seems to enjoy it. A great product to boost your cat's over all health.

Good L-Lysine paste for cats with a great tube design

Good L-Lysine paste for cats with a great tube design C 4 stars, but my cats are super picky about the chicken flavor
I got this 60ML chicken-flavored L-Lysine paste with taurine, Omega-3, and vitamins, and I'm giving it 4 stars. The product itself is well-made C I love the tube design because I can dispense exactly what I need, then twist it to suck any extra back in so nothing dries out or gets wasted. The cap screws on super securely, which is awesome.
It does seem to help with their immune support and the upper respiratory stuff that pops up this time of year C they're getting the benefits since I'm mixing it into their wet food and they eat it that way without knowing.
The only downside is the flavor/smell C my cats are finicky and absolutely refuse it on its own. They sniff it, shake their heads, and run off. Even when I try putting it on my finger, they want nothing to do with it and now hide when they see me get the tube out. I've had other pastes (like a maple-flavored one) that one of them goes crazy for and chases me to lick off my hand, so I know it's hit-or-miss with tastes.
Cats are just picky like that C some will probably love this chicken flavor, others won't. If you're thinking of trying it, go for it, but be ready to mix it in food if needed. Still a solid 4 stars for the quality, easy measuring, and secure packaging!

My cat likes it

My cat Shyloh hates it when I give her L-lysine, but she actually likes this stuff and will lick it off of my finger. I've tried MANY brands, and this has been the only one she would eat off my finger like that.
