Formulated and Approved by Veterinarians

VetriScience uses veterinarian feedback to develop condition-specific products for common pet health issues. Vetri Lysine Plus was designed to support your cat's immune system and normal respiratory function, and to help clear up watery eyes. The active ingredients help the body to repair tissue and produce the antibodies needed to fight infections such as URI.

Powerful Active Ingredients

The secret behind Vetri Lysine Plus is a synergistic blend of two active ingredients that support immune system function. The amino acid L-lysine supports the production of antibodies to help neutralize bacteria and viruses. It also plays a part in collagen formation and tissue repair to promote healthy skin and help heal wounds. DMG is included to strengthen your cat's immunity so she can ward off viruses and illness more easily.

Rated 5 out of 5 by Seems like a 5 ***** but just started today Omg chewy u rock! I ordered literally last night and my order was here TODAY. so nx day! Even with ordering late ....that is just awesome!! As to the Product,seems great. I have 5 kitties...all older ...except my newest baby and he's like 3 1/2 months old. Got him like a month ago and that is the little guy that brought the conjunctivitis Into the house....or caused my other babies to get it. Sighhh.....it's really stressful. Seeing the poor babies eyes watering and squinty like that. Little guy got drops and got over it finally after like two weeks. Now Loki got it last week and we took him to vet and got diff eye drops. And they ALLLLL HATE THE eye drops btw! SO WE TOOK LOKI BACK LAST NIGHT and now he is just gonna take the antibiotic liquid for 10 days. But Lexi also came up with this the day before. ... :( so I also took her last night and we decided on the Injection for her ,as we thought she would b difficult with drops or liquid. Anywayyyyyy all this led me to look up conjuctivitis for cats and it led me to l-lysine. And I found these chews here on chewy to try and HOPE it will ease them at least Nd by some long shot ,help the other two and prevent them from getting g it at all! Fingers crossed! Will update if they help! Also I got powder lysine from here but since they all love the treats...n long As it same amount...I think I'm just gonna send THT back and get more of these chews! Give em try...I have 5 kitties like I said Nd they all love thm! And that's with two being really picky :) October 27, 2016
Rated 5 out of 5 by Helped Tremendously My fiancé and I adopted a kitten a month and a half ago, and he has terrible allergies. I purchased these in the hopes that a bit of an immune boost would help to temper his constant sneezing and watery eyes since our veterinarian offered no help and just told us to deal with it. Our kitten isn't crazy about the treats, but he seems to like them well enough to eat them with his cat food - I give him one in the morning with his breakfast and one in the evening with his dinner, and it genuinely seems to have helped. His sneezing has virtually disappeared, and his eyes are significantly better. Overall, we have a much healthier cat. I would definitely recommend these to anyone who wants to give their cat's health a bit of an extra boost. The absolutely horrid smell that pours from the bag every time you open it is worth it.

Rated 5 out of 5 by Cat gave thumbs up! These fish-shaped bites are a lot easier to give than splitting a 500mg Lysine capsule and pill-popping it down my 19lb cat's throat. My cat is used to the Vetri-Science Renal Essentials hard tablet that I just snap in two and he gobbles it right down. These are more like a gummy worm so Lancelot just stared at it but wouldn't eat it. My solution was to refrigerate the entire bag, take the pill, snap it in two and then no problem. Now when I ask him if he wants his fish pill, he rings out "Meow!" October 15, 2016
Rated 5 out of 5 by Good Product I bought these for my cat who has developed allergies and asthma type symptoms. She is quite picky as most cats are but she loves these. I will be ordering again. October 18, 2016
Rated 5 out of 5 by My cat loves them! These chews are $28 at my vets office for the exact same size. My cat, who is very finicky, loves these chews. I can see a difference in his overall health. I foster kittens often and I am always so afraid that he may catch something from them. I like to think that this is a nice immune booster to prevent any illnesses. October 11, 2016
Rated 5 out of 5 by Excellent product! I have found this to be an excellent product for relieving symptoms of Feline herpesvirus (FHV, FHV-1). My two youngster kitties frequently cycle through phases of mild respiratory symptoms, particularly chronic slight inflammation around the eyes. These treats work! Most complaints for this product focus on moisture content of the chews, which does vary from bag to bag. Fortunately, the chews are pliable and can be broken apart and even shaped into smaller, more palatable bits. Please don't let the size or consistency of these treats dissuade you. If you have the patience to work with the chews, they will work for your cats! September 17, 2016
Rated 5 out of 5 by Smelly but healthy These treats stink really really bad...but they are so good for your cats. Every vet pushes Lysine but it's a pain to find the powder version of it not to mention it's pricey and mixing it into their wet food doesn't necessarily mean that they will eat it all - especially your finickier cats. My cat that is finicky loves them and takes them as treats - my fat one who will eat anything won't eat them at all. So in other words they are great but your cat may not thank you for them. September 14, 2016
Rated 5 out of 5 by Happy With Everything It's difficult to say how well the Lysine tablets I bought actually work as I have around 15 cats that simply come in out of the neighborhood to eat at night, so it's difficult to make sure each cat gets a pill and then to monitor their progress, but overall their coughing and throwing up has lessened. I am getting a second pack just to make sure they all get at least one or two doses. My shopping experience was excellent and the shipping was fast. September 7, 2016
