    Great Product; Great Deal

    My cat, Max, requires this powder since he's had an upper respiratory condition since he was in a pound where I adopted him 14 years ago. This helps keeps the condition at bay most of the time. Getting three jars of this was a great deal compared to what I'd pay at the vet's.


    Love the great service!

    I am a long time fan of Viralys Powder and give it to my 5 cats twice a day. They rarely have a sniffle! I just ordered from VetDepot for the first time and was thrilled with their super fast shipping and the price of the 3 pack. Thank you, VetDepot!

    I usually am very skeptical about supplements but have seen plenty of real support for using L-Lysine to prevent herpes flares in cats. And as a breeder, I have found that I have had far less, and less severe respiratory illness while using this product. I have used the measured pump and like it also, but with multiple cats the powder is more cost effective and easier to use; I mix it into their we food daily. The cats seem to accept this brand with no problem; I had tried crushing up pure lysine tabs because it's cheaper, but the cats would not eat it in food. Viralys is accepted by all my cats and I won't change again, not ever going without L-Lysine again!

    viralys Oral Powder for Cats, 100 gm (L-Lysine) - 3 Pack

    I am a cat breeder and when I tried going without using L-Lysine supplements for a while there was a dramatic increase in the amount of respiratory issues with my cats , I no longer dismiss this therapy as 'snake oil"!!! Every cat here gets it every day; I prefer Viralys to other products because even my picky cats will eat the food with this one; when the unflavored human powder was used, they would not eat it. The 3 pack powder form is the most economical for me.

    Supplements for me...supplements for my 4-legged overlords :-)

    I have a sable Burmese, and the breeder recommended that I give Nelson Viralys and a digestive enzyme product every day. What he gets I also give to his older "brother" Rocky, a shelter refugee. Seems to work as they very, VERY seldom need to be brought to the vet for other than the routine shots and teeth cleaning.

    Mix into their wet food along with the digestive enzyme and a natural vitamin/mineral supplement.
