## Description

Support your cat’s health with Lysine Immunity Health (new name, same great Vetri Lysine Plus formula), a vet-formulated cat lysine supplement designed to promote optimal immune function, respiratory health, and overall well-being. These delicious cat lysine chews combine 250 mg of L-lysine with DMG, two powerful amino acids that support antibody and collagen production, tissue repair, and healthy healing. Lysine supplements for cats also support proper calcium absorption to promote strong bones and healthy aging. Ideal for helping to manage cat allergy symptoms and respiratory discomfort, including sneezing, watery eyes, and nasal discharge, this lysine supplement for cats is easy to give daily or as-needed. The hydrolyzed chicken liver flavor is perfect even for cats with protein sensitivities - it's a taste that cats love! Whether used as part of a routine wellness plan or during periods of respiratory discomfort, lysine chews for cats can help maintain eye, nose, and lung health. Suitable for daily use in cats of all ages, from kittens to seniors, and for all breeds and sizes, Lysine Immunity Health helps build a strong immune response while promoting normal and comfortable respiratory function. Our dog and cat supplements are certified by the National Animal Supplement Council (NASC), routinely undergo third-party testing, and contain no hidden ingredients, artificial flavors, synthetic colors or preservatives.

Review: Great support for my cat’s daily wellness - I’m really happy with the VetriScience Lysine Powder for Cats. It’s easy to mix into my cat’s food, and she doesn’t seem to mind the chicken & cheese flavor at all—which is a big win. I like how simple it is to add into our daily routine, especially for supporting overall wellness. The powder blends well and doesn’t leave a mess, and the container is easy to use. After using it, I feel more confident that I’m supporting my cat’s everyday health in a simple, stress-free way. Overall, I’m very satisfied with this product and would definitely recommend it to other cat owners looking for an easy supplement to add to their routine.
Review: helping with my kitten's eye herpes - 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 desertcart if my cats have issues in the future.

### ⭐⭐⭐⭐ My cats love these
*by S***E on November 20, 2025*

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.
