Supports Immunity & Reduces Sneezing – Cats Love It 🐱
I’ve been giving my cat this Lysine powder for a few weeks, and it’s been great! She actually enjoys the chicken and cheese flavor, which makes it really easy to give her the supplement daily. I’ve noticed her sneezing less and her eyes and nose seem clearer, which is such a relief. The powder mixes well with her food, and the capsules are convenient for travel or when needed. It feels high-quality and safe, and the 60-count supply lasts a good while, making it worth the price. Overall, it’s a simple, effective way to support my cat’s immunity and help with allergy symptoms, and I’d definitely recommend it to other cat owners.

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.

These worked for my cat!!
He started sneezing periodically for 2 days, and I noticed one if his eyes was watery and a little red, he was tearing from that eye (clear tears). On the third day he started squinting and rubbing it. I read the reviews for these chews and figured I'd give it a try before taking him to the vet (which I am SO thankful I did). After ONE day he started sneezing less, on the second day he probably only sneezed once or twice and his eye was starting to look better. By the third day he was back to his playful ways, terrorising his sister (they love each other, really). I followed the directions on how many to give them a day, and will purchase again if the symptoms flare-up.

Disappointing to order cat food from Amazon US. Last time all the cat food got stopped by customs. Some went thru yet the food inside the cans became all watery and poor quality. I thought these health supplements would work better. However, the tablets inside became very dry and hard. Difficult to get my cat to eat them. Yet I paid a high price for the item. Disappointed!

L-Lysine contenant en plus de la DMG Diméthylglycine (appelée vulgairement vitamine B15) 2ème achat depuis avril 2019 JE CONFIRME SON EFFICACITÉ: Produit qui a beaucoup d'appétence au parfum très agréable - forme d'un petit poisson d'un peine 2 cm de long, facilement sécable en 2 au besoin. Mon chat le mâche sans difficulté: il en raffole. Mon chat auparavant avait les yeux larmoyant rouge d'irritation des canaux lacrymaux et mettait des gouttes partout sur le plancher, avec une tendance à sa moucher même si ce n'est que des éclaboussures claires. EFFICACE dès le premier mois de traitement: j'ai commencé par 1 "gomme" matin et soir pour tester si le chat supporte le traitement, puis au bout de 2 semaines 2 "gommes" matin et 1 le soir (le chat pèse près de 6 kg). Il n'a plus les yeux larmoyants de larmes rouges/marron. Je fais maintenant des cures de Vetri Lysine Plus occasionnellement suivant les récidives de cet herpès oculaire.
