Great product by Lisa from Piscataway, NJ03/30/2013

I have used this product for quite some time now to treat the symptoms of feline herpes. As always, it is very effective and my cat is happy and more comfortable.

viralys by life saver05/30/2012

this is the only product that gives your kid (cat) a chance of not chathing infections from other kids



Convenience by Tootie from Lucerne, CA01/18/2013

Have used this product before and its great. It is very convent to be able to order online. I'LL BE BACK.

Great Stuff by Madelyn from San Antonio, Tx03/11/2012

Our 12 yr. old cat had an infection over the Christmas Holidays. He wasn't eating which was totally out of character. The Viralys was instrumental in helping to get him well again. We are still using it. He likes it and has more energy than he has had for years.

Great Results! by Buzz11/01/2011

I have been using Viralys every since I got my cat who I later discovered has Feline Herpes. Feline Herpes is incurable but the Viralys keeps it in check. I use it with all of my cats to prevent the Herpes from spreading. They all love it and come running when it is time for their daily dose. The tube lasts a long time and I have three cats. I would recommend this product to anyone who has a cat prone to viral infections. Plus, I am getting it at a savings by ordering it from EntirelyPets.

Pleasantly Surprised by kittymom from Ohio10/23/2012

I had not purchased this product in a couple years and was happy that the consistancy is a thicker gel. My cat won't lick it from the end of the tube and now it doesn't run off my finger before I get it in his mouth. My cat seems to enjoy the taste, which he didn't like before.

My cat has feline herpes and this is the only thing that keeps his symptons in check.

Helped with my cat's herpes and asthma by Fluffy2 from Houston,Tx05/03/2013

My cat i rescued has herpes and asthma. Since. I have given him this on his treats, twice daily, he has improved. The cost here is exactly 1/2 from my vet and it arrived quickly. I was very happy. Thank you

Fabulous Value! by Loweern from Homestead, Florida12/06/2011

This is a product my cat will have to use for life and the price and service from EntirelyPets was superb!

Best Purchase by Cat04/05/2012

I adopted a cat from the rescue center. She has an upper respitatory disease and has to take the Viralys Oral Gel twice a day. I always order this product from Entirely Pets because I can get it cheaper through them, and faster than I can from the Vet I use. The Vet does not keep it on hand, so they have to order it, then the price is marked up. I would definitely recommend using Entirely Pets for any pet products you need for your pets.

Is it the same? by Baxter's owner from south Georgia06/22/2013

I have been using Viralys for many months as part of the treatment for my cat who has one eye that is affected by feline herpesvirus. Previous tubes of the material were very jell like and had a strong odor. My cat immediately ate it along with his food. This shipment, however, is much thinner and with less odor. The cat tried to avoid eating the part of his food that has the material on it. I wonder if there has been a change in the formula or if we received an out of date supply. I threw away the first tube and am waiting to see if he will get used to the next one which appears to be more jell like yet with less odor,,,, not sure I will reorder.

cat saving gel by popie from brookville,pa10/30/2012

I have many cats and when we took in a mother cat and her babies,we unknowingly got the herpes virus along with them.This gel has been key to keeping that virus under control.It controls the sneezing and upper respiratory congestion which is so contagious to other cats.I give it by way of syringe ,into the mouth,twice daily.If this is yuor problem,try this gel,it works well.

Really good product by catowner211/20/2011

This product helps to keep my cat's frequent upper respiratory infections under control. It also doesn't upset his stomach like other medications can.

Excellent product by LAJ06/24/2013

Nice to find the gel - most cats are not real big on "treats". This is a much better way to administer. Opening in tube fits into the back end of a 3cc syringe so desired amount can be given.

Good for chronic illness in kitties by sunryse1 from Oregon01/24/2013

I use this for my rescue kitties with URI. Works good.

Excellent Product by NC Cat Mama from Winston-Salem, NC02/14/2012

When I adoped my"Alfie" from the Humane Society I was not made aware that he suffered from FHV-1. After bringing him home I noticed his suffering and immediately took him to my Vet who gave the diagnosis. I use 1/2 tsp. (500mg) Viralys daily in his wet food to boost his immune system. It works wonderfully to keep symptoms away, and he is kept healthy, happy and playful. Don't hesitate to order this to help your pet.

Cheapest way to go... by Portlandcatguy02/11/2012

We treat our cats who have a feline herpes related virus that they caught at the animal shelter 4 years ago. This is the only treatment that disrupts the virus's replication. Keeps them felling better; but can't make them totally well. I get 3cc syringes at the drug store and load them with this product - directly from the tube. You remove the cap, slowly pull out the plunger on the syringe, put the barrel of the syringe over the tube opening on top - and slowly squeeze the tube until the syringe is almost full. Slowly re-insert plunger on syringe and recap product. Do this twice per day. This is the most effective treatment - this product is great.

my cats not losing her fur anymore by catlady from west virginia11/18/2010

my baby was so tired all the time,was shedding and she didn't keep clean. She was sneezing horribly Thought she had allergies. I never heard of Cat Herpes before this. Vet said bad tooth and ear infection was problem Paid a fortune to clean her teeth. They were not bad just dirty. They gave her antibiotics they didn't tell us she had herpes. Gave me this stuff told me to give to her. I did along with the antibiotics and she got better. However I Didn't do it regularly and she relapsed. Finally after third visit said she had Herpes and I needed to give to her even when she was well. I have been now for 1 month and she is better than ever. will give to her daily for the rest of her life. She acts and looks 100 percent better than before we started going to the Vet. This stuff is really good. She is eating 3 cans of food a day and She is not sneezing and she is wanting to play again.

Works by KR from Boston, MA07/28/2011

I have a 1 year old persian with the herpes virus. He has had chronic eye infections I think his whole life. I used this when I first got him as a kitten, stopped when his eyes got better but soon realized they need it even they don't show signs of an infection. So he'll be on it every day the rest of his life. He HATES the taste/smell so I use a syringe and squirt it in his mouth and he likes it that way.

by Anne02/07/2013

I was very happy with the service as it arrived only a few days after ordering. I use it continually with one of my cats per Vet recommendation and was glad to find it at a better price with speedy service.

Viralys oral gel by Jennifer10/15/2011

My kitten doesn't notice this Gel mixed in her wet food and after just 2wks use her eyes are less runny & red. (It is suspected she may have a herpes infection.)

Excellent Service by gizzy from NV03/14/2012

This product is the same as I had purchased from my vet during the office visit. I did not save a lot of money buying on line (what with shipping) but at least I didn't have to go back into the vet for a new supply. Overall, I rated this as excellent for ease of ordering and prompt shipping.

Great product by Rushatheart from NC04/30/2013

Very easy to give to our cat - he actually comes right over and licks it off the spoon without any prompting so we don't have to fight him to get it into his mouth.

Viralys Supplement by MWMWMW from Columbus, Ohio03/20/2012

My vet recommended this product for my cat and I really love it. My cat loves the taste and he seems to be more energized and bright eyed than usual. Love it! Love it! Love it!

A Must Have for a Healthy Happy Kitty by Kitty Mom from Charlotte, NC02/23/2012

I got my kitties at a cat rescue and within a couple of weeks my three month old female was in the hospital fighting for her life. I had never heard of feline ocular herpes and it had turned into pneumonia. After a couple months of Vet visits, hospital stays, and lots of nasty meds, I heard about L-Lysine and started her on it. NC does not have this product available in stores so I have to order it, but it has made a world of difference and I will never skip a day giving this to both of my cats. If I hear as much as a tiny sneeze from either one, I immediately up their daily dose. Abby has been doing great for more than two years now. I simply mix it into their daily ration of wet food, as neither one will eat it directly. I guess the only bummer is the so called "great taste" doesn't appeal to either cat.

Good Product by rjt from Wisconsin12/30/2012

Product works well for my cat with periodic sneezing due to upper respiratory infections surfacing now & then. 1/4 teas. twice daily for 2 ro 7 days, stops the sneezing. Do remember if your cat is doing more than sneezing, i.e., runny nose, sounding conjested, hard time breathing, etc. it will still have to go to the vet for possible antibiotics.

Great Product, Great Price! by Sarah N12/31/2012

When my youngest cat was diagnosed with Feline Herpesvirus, our vet recommended Viralys Oral Gel For Cats. He wasn't fond of it at first, but now he comes running to it every time he hears the cap pop! Since taking Viralys twice daily for a year, he has not had another FHV flare-up. I used to need just one tube every few months and bought it from our vet's office -- but at a fairly high price. So when my other two cats were also diagnosed with FHV, I knew that I would need a more cost-friendly way to provide for their long-term preventative care. I went searching online for the very best deal on Viralys Oral Gel For Cats and found it at EntirelyPets.com!

Have to have it! by Kat01/21/2013

One of my two cats, who were rescued from a shelter as kittens, has always had chronic upper respiratory infections and a permanent wheeze. It's a condition that vets have never been able to cure, they've only been able to treat the individual occurances which have been many. There were times when he had so much trouble breathing, I was afraid he wouldn't make it. The last time he came down with an infection, a new doctor prescribed Viralys. I began mixing it into his food twice a day. It's been a few years now and since then, I have not had to take him to the doctor for any infections and I no longer can hear him coming because the wheeze is gone! Have to have it!

Most reasonable price for product by catlover50306/03/2012

This is a produce I had prescribed by my vet for a persistent virus that several of my cats could not get rid of. It is a great product and by buying it on this site I paid about half the price.

Keeps the Doctor Away! by moxie07/27/2012

This seems to be an excellent source to fight off the Herpes Virus. Both of my cats take this with their canned food for breakfast. Neither cat turns their nose up to it! Very kitty friendly and it's affordable.

Good Price by gloworm from Alabama01/20/2013

One of my cats will lick this from my finger but the other one has to have it stirred into his food. Good price!

Feline "cold" symptoms by Tootie from Lucerne, CA03/01/2013

This product relieves or decreases cold signs and symptoms: sneezing, runny nose, and decreased appetite.

Viralys It works by Cindy from Salem, NY01/18/2012

My cat, Gremlin, has been on Viralys for about a year. I can see about a 75 % improval. I was getting it from my vet but it is easier to order it on line. It works and I will keep on giving it to her.

Excellent service and pricing by gizzy from Las Vegas11/16/2012

My first supply was purchased from my vet when both my cats had respiratory problems as a prescription drug. I was surprised to learn that I could purchase it on line which was much less even including shipping. I am very pleased with this company. Your order is filled immediately.

Fantastic by Kitnkprs from Bluff City, TN03/03/2013

Gave this to a foster cat with suspected Herpes and runny eyes. She eats it right off a paper plate and since she has started taking it, has not had any flare-ups with her eyes.

works wonders by tinytribble1 from Branson, MO06/22/2013

I have 2 inside cats and 5 outside kittens that were left by their mommas. All have some sort of upper respiratory issue. 1-2 doses a day, and they are symptom free for hours. Our vet recommended this for any cat with or without symptoms. It really helps boost their immune system.

by from 03/07/2012

This item is the same product I get from my vet and it's half the price.

A Must Have! by Kertra from Dixfield, Maine02/07/2012

Long story short I found what I thought was a kitten a few months ago and the vet said she was a cat not a kitten and severely malnurished from birth. He prescribed Viralys to help boost my cats ammune system. after receiving a couple shots. Within a week the cats repitory system seemed to be improving and when the antibiotics ran out I stopped the Virayls as well. After a return visit to the vet it was decided that Viralys would become a way of life for my cat. As long as she has it each day she acts and looks like a normal cat. One healthy kitty equals one happy customer. Will order again.

Best Purchase by Olivia from Punta Gorda, FL04/14/2013

My cat has to have this supplement twice a day. It cost more to get it from the Animal Hospital where she gets her shots and treatment if needed for any other issues. I have been using Entirely Pets for a while now, and I like the way they respond to my orders. I have never had a problem with this product and I will continue to purchase it through Entirely Pets

Save my kitty! by Manny from Cheviot, OH10/25/2012

This is the only product I know of for treating Herpes viral and saving my cats eye sight, Since he has been on Viralys' his eyes have really come into showing their beautiful gold color and he has had no flare ups in over a year. I am thankful for this.

by tinytribble101/30/2012

Works great for my cats that have upper respiratory issues. I only wish it came in a larger tube!

by Thai02/24/2012

Purchased for a friend who swears by Viralys Oral Gel and needed more. Was received much faster than anticipated.

Good product by Rox05/29/2012

Easier to administer with a syringe; seemed to help conjunctivitis in rescued cats. The cats would not accept lysine in chew/treat, or crystals (sprinkled in food), forms.

Best price and service by Animal fancier11/21/2012

Exact product as purchased at the clinic, but at half the price. Excellent and prompt service.

Makes my life so much easier! by 13Persians from New Hope, PA03/05/2013

I bought this instead of having to syringe powdered lysine and water to my cats twice/day. They seem to choke when I have to do that. They have feline herpes (upper respiratory problems). This is so easy, I just put some on my finger and wipe it on the roof of their mouth. They don't seem to mind it at all and it makes my life easier and theirs too, since it stresses them out less.

Works Wonders in Cats! by Spunkygal from Cullman, AL02/01/2013

I have 18 rescued cats so colds can get passed on easily. If I hear too many sneezes the cat gets 1-2 cc of Viralys twice a day. Most times two days later they are well! Also I have a FIP cat & one with possible Herpes - they both get Viralys & Interferon - I believe it helps them a lot and prevents a lot of other problems. All my cats tolerate the gel pretty well - I have found it works best to use a syringe - remove plunger from a 3cc syringe (no needle of course) squeeze desired amount into the top - slowly reinsert plunger and then you can easily squirt into their mouth. That way you know they got exact amount. WAsh syringe, spray with 10% bleach solution, and reuse. Some people put the gel on their finger, but for my cats a syringe works better. One tube lasts quite a while despite using it every day on multiple cats. Cuts down on Vet bills! It won't cure a bacterial infection but it sure helps them fight off a cold virus. Would love it to be cheaper - that's why only 4 stars - but it is a valuable asset for your cats and I highly recommend it.

It Works! by tgl11 from midwest07/25/2012

We took in a tiny abandoned kitten with severe upper respiratory problems last summer. Viralys gel seems essential in maintaining his well-being and Homeo Pet Nose Relief adds an extra boost. He gets two doses of Viralys daily. His quality of life is much improved, probably saved, by these products.

It is a miracle by Lisa from Houston,Tx03/20/2013

I read online about this supplement for my cat that has herpes with asthma like breathing. My cat was breathing so labored, I thought I was going to come unglued watching him suffer. My vet told me to try this before having to give him steroids. It's a miracle! I give him the gel on treats & his breathing became better in a week. I give him the recommended dose. Try this and I hope it works as well for your cats. I am very grateful.

hate the taste by romeo from pittsburgh04/25/2013

this product did not appeal to my cat at all. not directly into the mouth (spit out all over) not put into the food (wouldnt eat food). we switched to chewables and all is well.

Viralys by kendracw12/05/2011

This stuff is so awesome!! My cat eats it off a spoon like a treat. It seems to work for feline herpes too!

Great price by Melissa from Canton, OH04/22/2013

Great price, fast shipping on a product that was recommended by my vet.

What the doctor ordered... by Sam from Ohio06/24/2013

Meow: I don't like to talk about this much, but I used to live a pretty wild life style, before I hit "rock bottom" five or six years ago. When my owner found me, I was living on whatever I could catch and my eye was swollen up from a bad fight (still not sure who started it, but I sure lost.) Anyways, according to the doc, I got a little case of Herpes in that bad eye, and this Viralys stuff controls the symptoms. It doesn't taste too bad, and as long as it keeps my eye clear, I don't mind it much. If you got Herpes, you need this stuff.

My Kitties Like Viralys by Fiona's Mom07/17/2012

I have two cats that need to take Viralys because of the Herpes virus. My cat's eat it in their food each night and Viralys does the job.

GO DADDY by from GO


Great Price, works well by Chris from St Clair Shores MI02/03/2013

I purchased this when my cats were diagnosed with Chlamydia, and the associated herpes virus that goes along with it. Results take up to a month, but I feel the gel is much more enjoyable than the paste for my cats. All in all good product, fast shipping time

price can't be beat by lag1055 from pittsburgh10/07/2011

have to give Lysine to my 2 cats each day for life to treat eye herpes. Price is half of what my vet charges. Great deal and now with what I save I can treat my babies to all the treats they want !

Best L-Lysine for Cats Great Price by SMcc04/03/2013

I rescue and these cats have hidden exposure to the calici virus which causes Herpes and upper respitory. I've been able to give this twice a day (as they shed it every 12 hours through urination) and I see results. depending on the severity, i see at least improvement throught the process. You can go to Revival Animal on line and get 10mm feeding syringes really inexpensively and they fit in the end, if your cats won't take it. Most can eat it mixed in food and it's gone. GREAT PRICE.

Benefits of Viralys by Katlover from Cleveland, TN04/03/2013

Three years ago I rescued a Maine Coon kitten, Denali, from the local shelter. She soon developed an eye infection. My vet diagnosed herpes of the eyes which she said was common for shelter animals. An antibiotic cream cleared up the immediate problem but my vet said the herpes was incurable and to give her Viralys twice daily to help boost her immune system to prevent future flareups. And it has worked with amazing success and she loves it! She licks it off a spoon as if it's a treat.

Viralys Gel by df1657 from OK04/01/2013

My cat, Sadi, has the Herpes Virus, so has been on Viralys for several years to deal with the immunity issues she faces. In the past, I've purchased this through my Vet's office. This product, through Entirely Pets, is less expensive and is delivered right to my door!

feline allergies by berni01/15/2013

My poor Cinnamon has severe food allergies. Although he was on the special hypoallergenic diet, the allergies were getting worse. Viralys was recommended by the vet. It made the difference for Cinnamon. Now, he can eat a more normal diet without having ear and eye infections. It's not expensive and is definitely worth the small amount it costs.

Best price by Marilyn from Santa Ana, CA03/17/2013

I have several cats that take Viralys Oral Gel twice a day and I have not found a company that has a lower price as this one.

My kitty can't live without it by sasspot02/22/2012

It really helps my little kitty with her herpes of the eye. When she is not on this the problem is 10X worse. Thank you!

works great by Redseawitch from Salem NY11/09/2012

My vet recomended it for one of my cats. She has a form of herpes and it has helped her.

Very Pleased with product by Birman Lover from Chicago, IL05/06/2013

Product is well priced compared to buying from the vet...works well, and is liked by my cat.

worth a try by wendy03/20/2013

it is all whether or not the CAT will eat it. one will, the one who needs it - won't.

by Irescuecats02/19/2013

My Vet recommened this product for my cat. She has chronic sneezing with a runny nose. It has helped to minimize the flare ups during the winter months eliminating the need for antibiotics. I also recommend this product because its easy to administer. My cat will lick it off my finger but can be added to food, too.

Miracle gel by Kat04/08/2008

My little kitty, Micah, has had trouble with sneezing and panting when he plays since we brought him home from the shelter at 8 weeks of age. A friend suggested we try this, since it's likely that he has a herpes virus, and the symptoms cleared up right away. Now, he's a healthy and happy kitten that can play to his heart's content.

this is a good purchase, Love Love the price by tackettteri from Ashland, KY01/25/2012

this is what the vet put my cats on, they seem to like the taste

The way to go... by Lou Lorenzi-Prince05/06/2009

This gel works well and is the most cost effective dosing method. It can be somewhat messy to use but it wipes up easily enough. I was considering the pre-measured syringes but they cost four times as much to use - so they're out of the question.

Essential for our Peanut by Peanutsmom from Fort Worth, TX11/29/2011

Our little Peanut has feline herpes and Viralys is the only thing that keeps it under control. I put it on her canned food and if she decides to be fussy about what she eats, she'll start to show brown "guck" under one or both eyes. As soon as the drops kick in, the guck goes away. She'll be on it for the rest of her life, so I hope the price does not go up any more.

by Anita03/16/2013

This is excellent for runny eyes and for herpes in the eyes....We have one little one who is several years old who won't eat the treats but she will let me put this in her mouth off my finger...

Great Product for Finicky Cats by Deborah01/18/2011

I have a cat that will not eat any treats so this works great in a syringe. My cat has not been ill since I started giving him this product. Wonderful, wish I would have found it sooner.
