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.

Using For Part Of a Feline Herpes Virus Control Regimen
I purchased this and a list of other items because we took in a kitten that had Feline Herpes Virus and was constantly sick. He was getting our other 3 cats sick as well. The list I purchased was: 1) Tomlyn Scientifics L-Lysine Health Supplement Powder for Cats, 100gm 2) #1 Probiotics for Cats - Cuts Litterbox Smell - Stops Diarrhea, Guaranteed - 4X Servings, 50X CFUs 3) Vetri-Lysine Plus For Cats, 120 Bite-Sized Soft Chews - 5.29 oz 4) FELINE GREENIES SMARTBITES Healthy Skin and Fur Treats for Cats Salmon Flavor - 2.1 oz. ** I only give the supplements in the evening when I feed them the mushy cat food. I give these to all of my cats as they share and fight over the mushy food. So far the kitten has been improving. Before taking this he was sometimes lathargic and hot feeling like he had a temp. Also he had lots of yellow stuff coming out of his nostrils and eyes. I've been giving this to them for over a month now and he only has harder eye buggers, a little red around the eyes and he still sneezes. I have not seen any more of the severe yellow discharge from nose or eyes. As for # 3 on my list, I gave that 4 out of 5 stars because only two of my cats will eat them and the kitten isn't one of them. The one thing I must say from using the 4 supplements that I purchased, it seems like it gives the cats a burst of energy or something. The kitten normally tears around the house soon after eating the mushy food with these added into it. It also seems to help my 12 year old cat. She seems more active and not as crabby.

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.
