Trusted Immune System Support
Adding L-lysine as a supplement to your cat's diet is an easy way to help support her long-term health. As a market leader with a wide range of L-lysine products, Vetoquinol puts this active ingredient in tasty chews and bite-size morsels, plus paste, gel and powder form so you can find the best way to offer it to your kitty. These supplements are specifically designed for felines to support the immune system, and maintain respiratory and eye health.
Specially formulated Enisyl-F was the first lysine-based nutritional supplement developed for veterinary use for kitties. It helps support normal respiratory health, helps maintain normal eye function and health, and is recommended for immune system support and conditions responsive to L-lysine. Choose from three formulas, including chewy treats, bites and an oral paste.
Veterinarian formulated to deliver just the right dose in a treat with cheese, chicken, liver and hickory smoke flavors.
Tiny mouthfuls of L-lysine disguised as a delicious snack with savory chicken fat and chicken liver.
Highly palatable paste that can be given by mouth, mixed with food, or even applied to paws for your cat to lick off.
Supplementing with L-lysine is helpful for managing the symptoms of upper respiratory infections in kittens and cats that were strays, and those in shelters. For a highly palatable source of L-lysine HCl, try one of the Viralys formulations, made to support a healthy immune system and conditions that are responsive to L-lysine.

The cats & I suffered through several tubes of Viralys as prescribed by the vet. Maple flavor for cats, really? Not mine! After reading a review of Enisyl-F with tuna flavor, I decided to try it. I was leery of the dispenser, but It is super easy to use. You can tip the tube down to apply the paste wherever you need (I put it right on top of the cat food and it is enthusiastically licked off, no problem). This stuff is great!

I've tried a lot of different lysine products with my FHV cat. This is a great product in that it works, she just hates the taste. :( I found it helpful to get it down her by just squirting it in her mouth from the bottle, or via syringe. I wont be buying it again just because she doesnt like the taste, but if she did I def would.

I thought this would be easier to administer to my cats. They don't want it forced in their mouth. they don't want it put on their nose and putting on their paws just gets it all over the place. Everywhere but their mouth. I am sure it is a great product. Getting it into the cat is another issue though.
Helps with many medical issues

Lysine chews (liver flavor) and pump (fish flavor)are key to treating my little girl cat with a chronic upper respiratory condition. After I adopted her, it took a little more time and blood work to get her settled on a combination of meds that work! Lysine is a key component along with a steroid to helping her breathe better and limits the snoring, sneezing and snot. I can tell she feels so much better!

I use this for all my cats immune system. One has feline herpes and was on his deathbed when I rescued him. After antibiotics. I put this in his wet food and he has had no more outbreaks
His immune system is great. I
Lysine works wonders

I use this because I have two cats with an upper respiratory disorder. This keeps their symptoms at bay and their symptoms such as a weeping eye and nasal discharge is minimal. Unfortunately they are chronic and it is not meant for a cure but it does help relief symptoms.

the formula seems to have changed - it is thinner & lighter in color. Also - my cats don't care for it where the first batch they could not get enough of it - waste of money if they won't eat!!!!
No problem with service from Chewy - but they need to stay on top of formulas from manufacturers - not getting the same quality
cats won’t eat it

Neither one of my cats will eat this. I even snuck it into their wet cat food and they won’t touch it
Easy to use

The pumper delivery makes this super-easy to use. Most of our (4) cats like it, of course one has to be different and we have to mix it in their food
The tastiest Lysine for kitties
on Feb 7, 2020
This oral paste is nice and stinky, flavorful. My kitty happily laps it off my finger like a treat. We tried clear gels, but they were a chore. This is the winner!
