Review: A good supplement!! - I have used multiple tubes for my cat upon my vets recommendation since he was a kitten and now he is five so I can safely say this helps to keep his coat smooth and shiny and also helps with his overall health, energy levels and gut health I feel. He takes this easily there are no offensive smells attached to it. Check with your VET before you start.
Review: Boosts immunity, helps pets, great product! - Lysine is an immune booster & very helpful for immunocompromised cats & dogs. My vet prescribed lysine for my dog that I measured out & sprinkled on his food. Then my 21 yr old kitty caught a cold while I was sick too & vet prescribed lysine in this gel Viralys form daily for him in his old age to help keep him from getting sick. He lived to be 23! The gel form is much easier to give to cats & they either like the flavor or can’t tell when it’s on their food (I’m not sure which); & can be put directly on the tongue if using a syringe. I just put a 1cc needle-less syringe to the tip of the Viralys tube & draw while squeezing a tiny bit on the tube & no waste/no mess. I just put 0.5cc on top of my kitty’s canned food once a day & the tube lasts quite a long time for 1 cat, so not bad! Sadly, he was my little antique by time he reached his 23rd b-day & departed. I’m now using Viralys to help keep a FeLV very immunosuppressed cat from getting sick (along w/ no exposure to other cats or any sick people & keeping her indoors only) so she can live a happy life as long as possible w/o succumbing to every virus & bug that comes near. It’s a challenge but one of love. So I immediately started her on Viralys in hopes that it might help even in this severe case. For most pets, this is hands down a very good choice!! The verdict is still out in the case of the cat I’m trying to help that has essentially no immunity at all, but it sure won’t hurt her & just might help a little too. I do know it’s a great product from my own past experience & also because it was vet reccommended for my sweet ancient little guy as well as previous knowledge & use of lysine for people & dogs.

## Questions & Answers

**Q: VERY finicky cat, won't eat human food or any treats.Bought Oral Gel for him, given with syringe.  Any thoughts on how to use a different medium?**
A: I mix the gel with dry food and water. My cat is obsessed with it. It’s easy and doesn’t require any additional products!

**Q: What is the protein content per dosage?**
A: From what I see on the tube I have, there is no "protein content".  This is strictly an oral lysine nutritional supplement.  Each 1/4 teaspoon is 250 mg. of lysine.  I give my 2 young cats, plus my older 14-year old cat 1 dose every single day.  They are extremely healthy.  According to our vet, she recommends all cats have this every single day.

**Q: My cat has an upper respiratory infection and sneezes all of the time, will this help ?**
A: my vet and the specialist vet I go to for my cat recommends this for my cat's feline herpes virus. The signs of this virus is sneezing, eye redness, mucus in the eye, runny nose and respiratory problems. on top of all these problems my cat also has allergies and asthma that she is getting treated with steroid meds. the active ingredient in this product is supposed to help with the symptoms that flare up. And is also supposed to make it longer between flare ups. please note that this product is meant to be taken every day so it can build up in the cat's body.

**Q: what is the difference between your oral paste and this Gel besides the cost?? thank you**
A: Both products give the same beneficial lysine.
Viralys gel is maple flavored and comes in a tube that you squeeze out the approximate dosage. 
Enisyl-F oral paste is tuna flavored and comes in a metered dose pump. Each push if the pump gives exactly 1 dose of 250 mg of lysine. 
Hope that helps.

### ⭐⭐⭐⭐⭐ Helped my cat
*by M***R on November 3, 2025*

My vet recommended this for an outdoor cat that I had brought indoors. I was skeptical but it actually worked to clear up her congestion and watery eyes and she gained weight. I can't say that she really liked it despite the maple flavoring, but the main thing is it worked.
