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.

Executive summary: This product is twice as expensive as the 6.35 oz Enisyl-F Lysine product for equal doses. I compared the 6.35 oz Enisyl-F Lysine with this product, Vetri-Lysine Plus, 120 chews, 5.29 oz. At the time I bought both, the Enisyl-F Lysine product cost $12.00 and the 120 chews cost $16.81 (free shipping on both). The only way to effectively compare prices is cost per dose. This required counting the number of chews in the Enisyl-F Lysine product: there were ~430 chews in the 6.35 oz package. Since the dosage is 5 chews for 250mg of Lysine, it works out to 86 doses, or 14 cents per dose. With this product containing 120 chews, the dosage is 2 chews for 250mg of Lysine, so 60 doses. That works out to 28 cents per dose - twice as expensive! Having said that, I still like having both products around, but I mainly use the Enisyl-F Lysine since it is half the price. If my cat is having a bad day with his eye weeping, it's easy to also give him a couple of the "120 chews" to boost his dosage. My vet said that 250mg is actually too low for weepy eye problems related to herpes, and recommended at least 500mg per day. He said there was a study that 1000mg per day works even better for eye problems related to herpes, but I feel like that's a bit excessive. So I put a handful of these chews - 5 to 10 - in Yuri's food and maybe boost it with a couple of the other chews as necessary. I only rated this product with 4 stars because I'm not sure how much Lysine is actually helping with weepy eye. It's one of those problems where there are good days and bad days, so it's hard to tell how much it helps. But it seems to be a little better with Lysine, so I keep my cat on it. Update 9/27/2013: My cat Yuri was never diagnosed with herpes via an eye swab test, because they have to put them under and stick a swab under their eye. Instead, the vet tried several different eye ointments with antibiotics and none really worked great, so the conclusion was that he had herpes. He did better on the ointments or gentomycin eyedrops than without them. When the last bottle of eyedrops ran out, my vet said I could also try human eye drops. Even without Lysine, Yuri does just as well or better on human Allergy Relief eye drops, one in the morning and one at night, as he did on antibiotics. A different vet did mention that it could be a blocked or deformed tear duct that made his eyes water, so who knows? But the human eye drops are working great to control his tearing. I also switched from Iams cat food to "Before Grain". I always had to coax Yuri to eat the Iams, but now that he is on BG, he eats great and is much healthier overall. The price for BG on Amazon is about the same as Iams in the grocery store: $2/lb or so. Highly recommended.

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!

I have five cats and at least three of them have eye herpes. One of them is a 10.5-month-old rescued kitten I got last month. I am fairly certain he had eye herpes before I brought him home, but at any rate, there is a bit of kitty stress in my household right now as he integrates himself, so one of my other eye herpes cats may have been shedding the virus and infected him. Thankfully, he does not have ulcers, but he has clear eye discharge and sometimes sneezes. So I asked my vet about lysine options. Please note: this has chicken-based flavoring in it so it will not work for cats with chicken allergies and/or inflammatory bowel disease. (If you have a cat like that, your best bet is buying lysine tablets for humans and crushing them, then suspending them in liquid, drawing up in a syringe, and administering that way. Human lysine tablets are a bit too big for a cat to swallow.) If your cat is able to have most treats and such, these chews are a far better (as in, more pleasant for the cat and easier to administer) option. Anyway, the herpes virus requires a lot of the amino acid arginine (which has a long carbon side chain and a positively-charged nitrogen-containing group on the end) for replication. Giving lysine (which also has a long carbon side chain and a different positively-charged nitrogen-containing group on the end) in large amounts means lysine is taken up more by the cell machinery producing viral proteins. Only, when lysine is incorporated into viral proteins in place of arginine, the proteins don't fold properly and don't function as well (or at all). (This is true for human herpesviruses as well, so if you tend to get cold sores, take lysine tablets. It is an amino acid that you would need anyway. Just follow dosing instructions on the bottle.) So, in order to get my kitten's eye herpes under control before he starts scratching at his eyes or something, I am giving him this. He's been on it for a few days and it seems to be helping. He has less eye discharge and I haven't heard the sneezing for awhile. He's also not scratching at his eyes. He's still skittish so I just throw a treat or two on the floor in the morning before feeding him. I do this when he's hungry so I know he will eat these. He likes them and doesn't have much trouble chewing/eating them. (They're what I would call "semi-moist." They don't have a strong smell.) These are not causing my kitten any digestive upsets, which of course I'm very happy about. The bag is resealable to preserve freshness. If your cat is walking around with one eye closed or you see the third eyelid covering a large portion of the eye, there is probably an ulcer. You will need to take your cat to the vet and get a fluorescein stain and some antibiotic drops or ointment. This product will not cure ulcers. (I've seen the extremes of cat eyes damaged by eye herpes and you do not want to go there. It is expensive and requires many trips to the veterinary ophthalmologist.) Ulcers must be treated quickly and appropriately. But if your cat just has some discharge and sneezing and you have reason to believe s/he has eye herpes, these treats can help. Anyway, I'm very happy that these are working. Nice to know I can get them from Amazon if my cats have issues in the future.

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.

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.

Harder than the previous brand but, after few days, our cat love them.

Quantità minima

Cat started to feel better after using them He had a skin allergy (had bold spots) Vet suggested those pills

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.

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!

Brilliant product, keeps my babys from illness
