Easy Immune Support That Cats Actually Eat
These chews have become a staple in my cat’s daily routine. Packed with lysine and DMG, they help support immune health, especially for cats prone to sneezing or watery eyes. I’ve seen noticeable improvements in less than a week — more energy, fewer symptoms, and an overall healthier vibe. The best part? My cat actually eats them like treats. No hiding pills, no mess. They’re soft, easy to chew, and small enough for even picky eaters. I’ve used them during seasonal changes, stressful events, and even just as daily maintenance. Pros: Supports immune system and respiratory health Cats love the taste — easy to give Soft texture, no crumbling or powder mess Effective for both kittens and adult cats No artificial colors or preservatives Cons: Needs consistent use for best results Some cats may be suspicious at first (but most warm up quickly) Bottom Line: This is one of the few supplements that actually works and doesn’t feel like a battle to give. If your cat deals with eye discharge, sneezing, or just needs an immune boost, this is a game changer.

Rally loves them and his fur is so soft now!
UPDATE 3 years later- I stopped giving him these for no reason, and he has only had 1 flare up a year. I just bought some more as the vet suggested my cat always eat these. He ate this batch for a week, then he got really sick, stopped eating. I am pretty sure he got sick due to another counterfeit product (Nutramax Proviable DC bought through an Amazon 3rd party seller,) but since then he will not eat these, yet will eat the expired ones from 3 years ago. So, I am worried this might be a bad batch. The old vs the new bag smells very different to me. The new one does not smell better. Both are moist, so it's not that. One could assume that is because one is expired, but I feel there is more to it. I contacted the manufacturer and they suggested to only buy from Healthy Pet or chewy.com for they sell directly to them. I got a 3 month old kitten from the shelter. They said he had upper respiratory infection and gave me some pink medicine to give him for 7 days. When I took him home, he sneezed a few times that day. Then, it got worse the next 4 days as he was all congested, sneeze attacks, snorting while eating food. His eyes weren't too watery as I've seen others say. He just sounded miserable when sleeping. I even ran the shower on its hottest and held him up in the room for a bit. But luckily he still had lots of energy and was scarfing down all his wet food. A friend of mine told me about this product so I got it right away. I am sure the medicine really got him better, but I really think these helped. And hopefully help prevent flair ups. He loves them. He thinks they are a treat. I give 2 a day and break them up into 3-4 pieces. His fur got so soft! Has to be because of these. I highly recommend them.

Did the job in promoting wound healing.
My cat does not have herpes but is very old at 20 (nearly 100 years old in human years), frail and thin. It's been a struggle to keep weight on her and she heals much more slowly than when she was a youngster. Out of nowhere she developed a swelling on her cheek and by the next morning she had an awful allergic reaction to what turned out to be a spider bite, which popped open spilling fluid mixed with blood all over the place, and morphed into the worse looking 1+ inch diameter lesion I've seen on an animal. She's petite and only 4 pounds, so for her, this was huge. I started applying Neosporin 3 times a day and began the Vetri-Lysine Plus chews after reading that lysine can also be used for animals, that it was very beneficial for boosting the immune system and for wound healing. It's been 6 days now and she's been on the lysine/DMG for only 3 days but it's like a miracle. The lesion is now about the size of a dime, all dried up and with no swelling. She's so much better, eating more than usual, purrs up a storm and is even playful. Hope the hair grows back, but that's the least important. Started reading more about Lysine and DMG in the last couple of days and am beginning to wonder if it might help her in other ways too. Her Vet said that her weight loss and frailty is a part of the normal aging process and that there really isn't much we can do. Maybe not, but if you read about what Lysine and DMG allegedly does for humans, maybe it can also help an old cat gain back some muscle and weight, improve balance, keep illness at bay, strengthen bones, etc. It'll be worth a try. Once completely healed, I'll probably keep her on it indefinitely, but on a lower dose and probably only 1 every other day to see if it helps in other ways. Currently, she's getting 2 chews a day (3 the first day) and luckily she likes them. Also read that too much lysine over a protracted period of time can cause liver damage in humans, so will keep a careful watch on the dosing. Some of the other reviews say that the chews really aren't soft, but they aren't hard either. They're pressed into very tight little fish shaped nuggets. They crumble a bit when my cat eats it, but she just licks up the crumbs from the palm of my hand.

My uber-finicky cat loves these!
I tried these, after debating for months and months. My cat that needs L-Lysine is THE MOST FINICKY cat on the planet! I was completely sure that he would simply sniff them and walk away. After all, he hates virtually every treat I've ever tried to give him. But, in fact, he LOVES these chews! He climbs my leg to get to them! Both of my cats love them, but he is the one that shocked me about it! I notice that several people talk about how chewy these treats are. My finicky cat is small (barely 7 pounds) and has such tiny teeth that they are almost invisible, unless you are within a foot of his open mouth. I don't break them up, at all. I simply toss them out of the bag and onto the floor. He scarfs them up and has no difficulty demolishing these treats. Now, my 18 pound cat inhales them, but that's another story! I waited a while to see if my uber-finicky boy would change his mind after a time. But he is only getting more and more crazy about them! It's like he is addicted to them. I'm here today to order a few more packages of them. Does it help his eyes where he has his herpes infection? Yes! His eyes have never been clearer. But, note, he has resistant herpes and I give him 3 chews twice a day, per his vet's recommendation, not the 1-2 that the company recommends. Expensive? I don't think so. These chews are a whole lot less expensive than the vet bills! Update: Months later and my finicky boy is loving these treats more than ever. I've found that I had to go up to 4-5 treats twice a day to keep his eyes clear, but that's fine. He has no side effects from this product. And the wonderful thing is that he no longer has chronic weepy and matted eyes and constant infections. I have never seen his eyes so clear and dry. It's a beautiful thing! And understand, this cat spent two months at a kitty ophthalmologist having one of his eyes debrided (excruciatingly painful!) twice a week and almost had to have his eye enucleated (removed) due to an out of control herpes infection, despite getting anti-viral eye drops every 2 hours around the clock, along with antibiotic eye drops several times a day, with no improvement. He has never been completely free of infection until I discovered L-Lysine. And he has never been this easy to medicate until I discovered these treats. If I could post his before and after pics, I assure you that you would be amazed! I'm not one to give praise lightly, seldom find much worth 4 stars, let alone 5. But if I could give this product 10 stars I would!

Caused severe constipation and a high vet bill
Unfortunately, I cannot recommend these! Our Vet had recommended these to support the immune function of one cat and he rejected them and mainly use them as toys to bat around on the ground. Our other cat loved these though and looked forward to her treats every evening. Unfortunately, after a bag and a half over several weeks, we ended up at the emergency vet with severe constipation. $600 later she is finally starting to recover, but after reading the reviews here we are confident that this is where her digestion issues stemmed from since she is almost 7 years old and has never had digestion concerns before.

Formula Changed. My Cat Hates It Now
I have been feeding this to my cat for the last 10 years. I give it to him occasionally so a large bag lasts me a long time. Checking back in my order history I last ordered this in April 2022. I just ordered it again in February 2024 and the formula has definitely changed since my last order. As soon as I opened the bag I could tell a difference. Previously the chews were darker in color, more dense, there was a consistent shape to them, and there was a definite smell to them that I thought was close to fishy. This latest batch I received was lighter in color, inconsistently shaped, softer, and there wasn't much of a smell and the smell it did have smelled like peanut butter to me. I already knew what was going to happen but since I paid for the large bag I threw a chew down to the ground expecting my cat to pounce on it like he usually does. He pounced on it alright but then did like a double-take and sniffed it and then said heck no and walked away. I then picked up the chew and tossed it across the floor which is usually enough to get him to chase and then eat a treat. He did start to each the chew this time but then spit it back out after only chewing it a few times. That was all I needed to know and it would be a waste of time for me to try any further with this. I have regulated this bag to the stray cat I feed so hopefully he will eat it. I am sad because this is yet another instance a manufacturer changes a formula and now my cat hates the product. Now I need to try to find a replacement which is not easy with stubborn cats. As I am sure a lot of people are familiar with, this is going to be an expensive trial-and-error process until I find a replacement product.

Excellent Product--works very well for the control of a wide array of herpes virus related cat health issues.
Yes! It will help! I have a Siamese, Maine Coon, Tabby, Mutt :) that has very bad nasal discharge and post nasal drip so bad that makes him throw it up with his food! Yuck! He was not getting any sleep over his continual coughing, sneezing, and throwing up. I gave up taking him the vet since they would just give him antibiotics that would slow it down for a bit and then it would come right back, so instead of allowing him to develop a resistance to the antibiotics I opted to wait until I could find a better answer. Within a few days of starting the Vetri-Lysine Plus his sneezing and stuffy nose subsided, and he stopped coughing almost entirely. I have to give it to him 2 times a day about 12 hours apart for best results. The added advantage is that the DMG worked to help reduce his sore kidney issue that I was dreading to take him to the vet for. Siamese are known to develop kidney issues, so I was pretty sure there wouldn't be much they could do for him since he is 14 years old. His kidneys don't bother him at all any more! I started giving all my cats DMG since they are all old. It is dosed out every other day with canned food from a bulk form of DMG I get from Amazon (he gets extra now) and I am amazed at all the problems it has cleared up. I haven't slept in almost two years, since I started taking the DMG daily I sleep really well, and I have been dreaming! After 20 years of no sleep to speak of, and trying everything there is to try--the DMG worked! The DMG is a really good reason to buy this version of L-lysine, other brands don't have it. My cat did not like it at first, but the other 4 did, so I had to force feed it to him. However, after he realized he could breathe better he no longer resists. He takes it twice a day without any argument now! The Rosemary is a product stabilizer used in place of BHA/BHT, which are 2 very bad chemicals. I'll take the Rosemary over the artificial stabilizers, so far have seen no ill effects in my cat from the Rosemary. I've been using the Vetri-Lysine Plus for almost 3 months now and my cat is doing very well!

Impressed by the results
My female calico who is getting to an advanced age was never fussy over the oral lysine gel we used to treat her. She would even turn her nose up at food we tried to mix with the gel to avoid administering it to her by hand, which could be a struggle. For that reason I was reluctant to try these treats but wanted something she could take that was less stressful for the both of us. At first it wasn't a success, but after luring her in with a regular treat and then rewarding her with another one afterward she was eventually consuming these treats without the need for the non-medicinal ones. After a week or so of two treats twice a day I noticed an improvement. My cat became more energetic and alert, and also stopped shaking her head and sneezing so often. The discharge from her eye only seems mildly reduced, but cleaning it up is no problem now that her overall health has improved. Needless to say I will be purchasing more.

Efficace
Un peu gros à mâcher pour mon chat alors je le mets dans son bol en le coupant en deux..et il accepte ainsi ! Efficace car ses yeux pleurent moins. Donc 1 poisson plus la lysine en pompe 1x par jour!
