Excellent product
March 27, 2023
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!

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

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.

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.

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.

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
June 1, 2015
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.

My cat's Ophthalmologist recommended this for China's eye condition (herpes virus). She has been using this for 4 yrs. She likes the taste so administering this product isn't a problem. She still has a lot of issues with her eyes, but I will continue to use this product for as long as she lives in hopes that it's helping her in some way. My only problem is that it's expensive. I have 3 other cats that also have this virus, but I can't afford to buy it for everyone.

Helps calm allergies in old cat
April 13, 2015
My older cat that developed allergies five years ago. Nothing helped, not even moving to a different climate/area. I've tried alternative therapies, changing diet, and regular therapies from traditional vets (shots). An alternative vet recommended Viralys and the L-lysine helps calm some congestion. Wish it was made with better ingredients and without sodium benzoate and artificial sweetener. The gel is easy to administer.

Both of my cats hate this gel. I'm disappointed as I'd hoped that they'd lap it up like Petromalt, but no such luck.

I used to get the Lysine powder, but my cat decided that she did not like that any more so I tried the oral gel and she seems to like this. This product keeps my cat's herpes symptoms in check. I put a little on a spoon and she just licks it off.

Best "vitamin" for my cats!!

When I adopted my new kitties from the pound, my new vet prescribed this when they had upper respiratory infections. It really helps their immune systems! You just put it in their food and they LOVE IT! Now, I use it all the time!! Can't hurt them! :)

ordered by vet
April 5, 2015
We inherited 2 cats and one was very sickly. After many months and a lot of money the vet diagnosed feline reparatory herpes. He sneezes almost constantly and has a poor appetite. But he is such a lovable sweet cat we had to do whatever we could for him. He gets this twice daily via a syringe. He does not like it but true to his disposition he takes it with minimal effort. He still has sneezing flares but not quite as frequent as without the medicine and at least we feel we are doing something for him. He is eating a little better and has started playing more which makes us think he is feeling better. Is the Llysine the reason we do not know but we will continue it if for no other reason than it makes us feel like we are doing whatever we can to help him because we love him so much

I bought this product hoping it would help the symptoms my kitty suffers from Feline Herpes. Thankfully, she just loves it and is on my bathroom countertop each morning and evening for her 'medicine'. Her symptoms have lessened since she's been taking it and I will be ordering more soon.

I have adopted a cat that has herpes and the vet tech at the cat shelter said to get this. When he starts sneezing, I give him this at least once a day. The sneezing stops. This is great stuff.

This is the best product I've found for treating feline herpes - it's easy to give because the cats like it, and it visibly clears up eye and nose issues, along with the range of other symptoms. The kittens and cats just seem healthier all around. I order this for a friend who rescues feral kittens and cats (who often have this problem), and it's worked really well.

helps FELV cats
August 28, 2014
I use this supplement mixed in with their canned food and a little water. They both like it best this way and chow it down. FELV cats often have the herpes virus that causes irritation to their eyes. This soothes the irritation tremendously. Entirely Pets has the best prices I've found for a fantastic supplement.
