My cat loves the taste!
My cat had many conjunctivitis and ulcers in her eyes caused by herpes. I've been giving her Viralys everyday as recommended by the veterinarian and she hasn't had any infection ever since.

My Cat Loves this stuff!
One of my cats, the one that the vet recommended take this product loves it and comes running every am for some! My other cats don't seem too interested to take it, but I know I could get them to take it if I needed to. It is a good product and was recommended by my vet. I am glad that the one who needs it likes it. The gel is easy to administer!

Helps me to feel better
My human got this on the recommendation of my doctor. It seems one of my house guests brought in an infection and I caught it. My human mixes it in with my food and it tastes good. It helps my immune system fight the problem and I feel better. I would recommend it wholeheartedly

Review for Viralys® Oral Gel 1.25mL/250mg - 5 oz
My cat needs this and it is much cheaper to get it from you then the Vet. He likes it and comes when we hit the tube with a spoon and he licks the gel off the spoon.

Vet recommended
I was buying this through my Vet for one of our cats. It is less expensive buying it from EntirelyPets.
A recommended product from our Vet. Cat eats it mixed with her wet food without hesitation.

Review of Viralys
This is a great product. I'm glad it's available for my cat who had herpes when she was younger. Thank you.

Java loves Viralys
When Java, our Burmese, was about 1 year old he would have issues with his eyes where he could not even open them. We took Java to our vet who prescribed Viralys for Java and refered us to a feline eye specialist. After several epesodes of his eye problems, we monitored his scratching his eyes with his back (Clawed) paws and trained him not to scratch his face. We also put Java on a daily Viralys vitamin supliment and diet change. Java is now thriving !

Love this stuff!
I've been using it for over five years to help with one of my cats weeping eyes - he doesn't care for treats, but takes this without much fuss. It works so well i've started using it on local feral cats that come around with runny eyes and noses; when their noses are stuffy, they have a hard time smelling the lysine treats so this really does the trick....I'll never be without this handy product again so have ordered in bulk - thanks, Entirely Pets - your great prices and easy ordering have been a blessing :)

Lysine for cats with respiratory problems
When the sneezing starts, I reach for this. I find it easier to dose a cat with this tube rather than the pump bottle.It is thinner & clear & 1/4 tsp equals a 250mg dose of lysine.

Product seems to work great
Works well for my male orange tabby who gets a "rat ulcer" which is a compromised immunine deficiency issue - on and around his mouth. Normally we have to take him to the vet for a steroid shot to get rid of his ulcers - but if he has another breakout soon after his shot - we have to wait out the steroids effectiveness. With this supplement it helps treat and speed up his healing process. All we have to do is smear a 1/2" line into his fur on his paws for him to clean off. I would recommend this product to any cat owner who has this issue.

A required product!
It drastically reduces the effects of chronic Feline Herpes Virus. Our cat would have a far worse quality of life without it.

effective lysine treatment
This is the first time I've used this brand of lysine.
After two weeks of religiously treating twice a day,
my kittens are completely over the goopy eyes &
sniffles. Some that I cannot get to more than once
daily are much better, but not totally over the
herpes flare-up yet.
This product, not being in a fancy pump container
is a better price. I will continue to use it.

works great for senior kitty
Sammy is 18 years old and had a bad upper respiratory infection. Terrible coughing, sneezing, and congestion. She's had this condition for about 5 years, and has been treated with various medications: steroids (caused diabetes), antihistamines, antibiotics. They all worked to some extent for a short time, but the problem always persisted. Finally, my vet suspected feline herpes. She gave Sammy an antibiotic shot (covenia) for the bacterial infection, and prescribed this product. Her infection cleared up and the coughing and sneezing stopped as well. It's been about a month and she's still doing well. Her appetite is back, and her energy level is great! She hasn't felt this good in a long time. Sammy loves the taste and comes running for her twice daily treat. I put it in a spoon and she licks it off.

Viralys Oral Gel
My cat loves this gel so much that she reminds me twice a day that it's time, lol. It has made her health much better. The vet initially sold it to me, but it's so much cheaper here.

Best Purchase and Service
Thank you for your prompt service as I was very pleased at how fast I received my purchase. My cat needs this product and you have made her a happy cat. I will continue to purchase this item with your company. Again, thank you and I will let others know of your company.

Good Product
I have two cats on this product. I have two more that need to take it, but it's too pricey, so two are on the gel and two are on lysine treats. I wish this was offered in a 3 pack or 6 pack, so maybe it would be a little more affordable. I use a syringe, but if some drops on her paw, she just licks it off. Evidently, the flavor and texture is better than the cheaper brand, which Patches hated. Viralys seems to be helping with the upper respiratory problem. China has severe eye problems (ulcer, sequestrum) due to the herpes virus. I will continue with this product for as long as China lives just with the hope that it's helping some.

Can I mix this product in with my cat's wet food or does it have to be given alone?
1 Answer
It is recommended that this gel is administered directly- but it should be fine to give with food so long as your cat ingests the full dose.

from pittsburgh, pa asked:
November 19, 2014
how many doses are in this?
1 Answer
Approximately 115 doses for a cat over 6 months of age, which should last just under 2 months for a single cat. For kittens under six months, approximately 225 doses, which should last about 3 and a half months (this is subject to change, as a kitten should be moved from 0.65 mL doses to 1.25 mL doses after reaching 6 months of age).
