my cats really do not love this product BUT it is very GOOD for them ... so we struggle
Easy to use; helps my cat feel so much better.
For local humane society
Great price and fast delivery. The L-Lysine works for my cat's watery eye and she likes the flavor as well.
Works well
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.
its very great product !
My cats are much healthier after taking this product. No more runny eyes, sneezing, and dandruff.
We sprinkle this on all the cats' food. It keeps them all healthy.
Love it great product and I have 1 kitty That's super picky eater
Viralys Powder L-lysine is THE go-to product for multiple cats for weather changes or when 1 of the cats comes down with a cough. It prevents the other cats from being infected.
Great product, fast ordering and delivery
best product ever!
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.
Safe, easy and effective to use. My little kitties responded quickly after using it!
Great product
This Helps My Teenie's Herpes In Her Eye.
Recommended by our vet for our cats immune system support and maintain normal eye function and health.
Effective, economical and easy to admin to my cats by sprinkling on moist food.
Bought this product to help Vinny's immune system. This will be Vinny's first try.
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.
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.
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!
Alive to offered the very best price on this item! I'll be back!
Great product. Very easy to use
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!!!
this has great results for all 4 of my cats or kids
Great product. My vet recommends it.
Great product for your feral colonies. Keeps those nasty upper respiratory diseases at bay. Good price too!!
price and ship cost
We have an FIV+ lovey cat who also has a weeping eye and has been taking Viralys Powder for about 4 years now, and yours was the best price!
I have 4 outside cats and I want to help keep them healthy. It's easy to use and they like the taste.
this product is easier to give to my cat then the paste L-lysine
Vet recommended this for all 7 cats.
Great product.
This was originally given to me by my vet and i was pleased to see i could order it online. My cat loves it.
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.
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.
Great product at a GREAT PRICE!
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.
This product helps my cats from getting the herpes virus.
My rescue feral has breakouts on her chin with regular use of Viralys we have no issues. Vet recommended it!
Cat has herpes and medication needed . It works if used twice daily
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.
My kitten has the harpies virus and this is supposed to work great.
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.
It's excellent support for my kitty and easy to give to the 'food motivated.' You can read about how I use it on my blog, Extreme Cat Lady.
I adopted my kitten from the Humane Society with an Upper Respiratory, this works wonders for him and his sneezing!
best supp for felines and best price for product
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.
Viralys powder is really easy to administer it helps lessen the signs of infection and reduce viral shedding
