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.

My cats love these
I have had my cats on these for years now, I’ve lost count of the amount of packages that I’ve purchased. This is the only brand that I will buy because it’s the only brand that my cats will eat. I have to cut them in thirds for my cats or they are too tough to chew and they won’t touch them. I cut the tail off and then the main part in half, perfect size for them. Once I do that they get excited for their treats. I got one of my cats when she was 10 weeks old and noticed that she was sick right away. The vet explained that she had a cold caused by the feline herpes virus. She’s twelve now and if she doesn’t get the chews then she’ll have a cold within days. A couple of years later, I adopted a two and a half year old male cat that also has feline herpes. Without these chews his eyes get junky and he gets the cold symptoms just as quickly. They both know when it’s treat time and will sit in front of the counter and meow until I look at the clock. I recommend these to anyone that has a cat with feline herpes. If your cats won’t eat them, try cutting them in half, it might help; did with mine.

Product changed - cat won't eat anymore
My cat was taking her heart medication in these treats for about 7 years. I had this on subscribe, but the last few months I received these, the treats have come hard and I have had to soak them in water to make them soft enough to actually mold the medicine into. They also smell different and while she still eats them, it's a pain to get her to eat them. I switched a couple months ago to another treat that is softer (and easier to put her medication in) and she likes those better, but it's not lysine which is supposed to be good for her heart. I recently ran out of that other treat and opened the last bag of this I received, she won't eat it at all anymore. I'm changing my rating from 4 stars (because originally this was the only treat she would eat her medicine in), to 1 star because something with this product has changed.

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.
