Excellent product

Ordered this for rescue cats who were having issues with eye drainage that didn't resolve with antibiotic treatment and the difference is night and day. I avoided the less expensive one because of reviews that cats didn't like the taste and I'm glad I did because this tube will last for months even with all the cats I have and they love the stuff. Highly recommend

Merchant Response:Hello Joy, That is great to hear, we are happy your cats are enjoying the product! Sincerely, EntirelyPets

positively my two indoor therapy needed with the higher temperature in the lower 90 degrees and with our higher humidity more than usual their sleeping nearer there feeding and watering station, when our weather cooler front in couple days we're all back to our usual craziness! order your particular; products due to the coronavirus madness, to aid and help them along daily to survive to have amazing loving life!
  • all good here worth waiting for exactly what I hope and expected!
  • Amazon was a little slow getting to us am guessing due to the United States Postal services holding all of the mail back several days due there oh personnel problems! When using regular or supposedly priority mailing doesn't help all they do keep raising costs with less service, I am hoping you keep using FEDEX, Uber, United Parcel Services, or DHL, Our mailing USPS has a new boss whichever knows whoever is doing this particular job is major huge budgetary cuts with less postal services delivering now some time were getting mail at 6 to 7 pm with our usual times are between 11 am to 12:30 pm Monday through Friday with Saturday now very inconsistent!

My Cat Loves this stuff!
August 9, 2017
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!

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

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.

Java loves Viralys
July 25, 2016
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!
January 14, 2016
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
January 12, 2016
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.

works and cats like it

Product seems to work great
November 3, 2015
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
September 27, 2015
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
August 3, 2015
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.

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.

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).
