This nutritional supplement works well on feline herpes, which is an extremely common upper respiratory illness in cats (also called rhinotracheitis virus). Cats living among many other cats or who frequent environments with other cats are especially susceptible to this virus.
For use in cats.
Viralys relieves symptoms and works to reduce shedding of viruses. It is an easily administered (simply sprinkle into your cat's food) and extremely palatable formula.
L-Lysine aids in minimizing and controlling feline herpes symptoms.
No known side effects
L-Lysine
Contact your closest emergency animal hospital.
Keep out of reach of children.
100 gm or 600 gm
Vetoquinol
Once a cat is infected with feline herpes, they are a carrier of the virus for the duration of their lives. This means flare-ups can occur at any time. Symptoms of feline herpes virus infection include sneezing, nasal discharge, and watery eyes. L-Lysine is an amino acid that has shown proven effectiveness against duration and severity of infections.
Each 322 mg (one rounded scoop) contains approximately 250 mg of L-Lysine in a palatable base. The suggested dose for cats over 6 months of age is one rounded scoop given orally twice daily. The suggested dose for kittens under 6 months of age is 1/2 scoop given orally twice daily. Adjust dosage as recommended by your veterinarian
 L-Lysine in a palatable flavor base.

I have been using Viralys powder for about a year now, and I have not had any more outbreaks of feline herpes in my two cats. They both love the taste. In fact, my youngest cat can't get enough of it, and I have to stop him from licking it straight from the container! I never want to be without this product.

My rescue kitty was recommended Viralys Powder by her Veterinarian due to the Herpes virus. This product boosts her immune system and helps to minimize recurring sinus and eye problems.

My poor cat has been coughing running eyes and the vet recommended this for him we are in day 3 he eats it mixed in wet food so we will keep it up for recommended time. Sylvester hasn't cough today at all we are so thankful.

This Lysine powder is an easy way to make sure my cat has the lysine she needs so she doesn't have a flare up. This is particularly true when we go away and leave a bunch of food out.

My male cat has feline herpes and his vet recommended this to make the symptoms subside. It is a great and effective product but not cost effective until now. My vet wanted to charge close to $100 for this medication. I'm grateful to have found a cost effective alternative to maintain my cat's health.

Allivet is a very reliable company and they have never let my cat or myself down by always being very prompt on their shipping and always having their products available

L-lysine helps shorten the onset of an upper respiratory infection and also helps prevent a relapse. Viralys powder makes it easy to add to kitty's food and is quite palatable. So glad I found this product from Allivet at a reasonable price and prompt shipping.

Depicted is the 100gm jar of 'Viralys', l-lysine powder. We actually purchased the large economy 600gm jar of the product. GREAT buy at an economical price, with a 'free shipping' bonus. 'Viralys' l-lysine powder is an important immune system 'booster' maintenance supplement to manage one of cat's feline herpes and successfully prevent herpes outbreaks. Allivet provided a great service to us!

I have more then one cat and keeping them on the viralys powder keeps rhino outbreaks at bay. I have been using it for about 3 years now and the results are excellent.

I got a very good price, it arrived 3 days early, and in minimal packaging, which is important to me. Very pleased with whole transaction.

Deborah H Verified Purchase

I have been using Viralys for my cats for many years. One of my cats used to get upper respitory infection which would mean a trip to the vets for antibiotic, etc. All my other cats would also get sick, but since putting this on their cat food twice a day, the problem was solved.

Susan A Verified Purchase

One of my cats was recently diagnosed with feline herpes and the vet suggested that I start her (and my other cats) on this product to try to improve ehr immune health. I had my order within a few days of ordering it!

Our youngest constantly fought runny eyes, terrible congestion, and incessant sneezing. We got this powder to sprinkle on his wet food in the morning and evenings and it did WONDERS. A couple days ago we ran out and decided to give him a little bit to see if he needed to continue with the powder or if he was okay without it. Today his eye is completely gooped shut and he's very congested and depressed. Needless to say, his new jar of powder is on the way!!!

Had a friend recommend this product for my kittens who were rescues and had respiratory issues. After the antibiotic was taken, Viralys seems to keep them from getting respiratory issues again.

Jean D Verified Purchase

I have several rescued cats who have permanent upper respiratory damage as the result of herpes. I'm hoping that the Viralys powder will ease the symptoms of runny eyes and noses.

This product is great for building a cats immune system. Mix with wet food or sprinkle on dry food. Works well for helping with upper respirtory infections and give daily to cat that are Fiv positive.

My Persian cat has Feline Herpes virus, which flares up periodically. Since I have other cats in my household, I wouldn't be without this product. I mix it in their wet food daily. I get the 500 mg size and Allivet has the best price around - I've checked.

ELIZABETH W Verified Purchase

I use L-lysine regardless whether or not, my cats have herpes virus. I place a scoop in their mouth daily and sprinkle a scoop over their dry food. They like the taste and it smells like fish. It really works well for their respiratory tract. It doesn't alleviate allergies, but it does help them have a strong immune system, so they can fight respiratory aliments quickly. It doesn't seem like they ever have the sniffles, runny nose or watery eyes when I use L-lysine everyday.

Viralys Powder While it doesn't cure the virus, it does help to manage it. It just takes a pinch mixed in with their food and it does the job. thank you Allivet.

Our vet recommended this product for our cat that has conjunctivitis. We were worried what she would think about white powder sprinkled on her food but she LOVES it. In fact, she licks all the powder off the food kernels before she eats them - very cute. And, we've seen a definite improvement in her eyes. Highly recommended.
