Viralys Lysine powder for cats is a safe and effective way to lessen pain of feline herpes virus, FHV-1. With L-lysine, an essential amino acid that works to suppress FHV-1 symptoms and recurrence, this powder is a treatment for symptoms of FHV-1 such as conjunctivits.

This L-lysine based, developed specifically for cats and kittens who have or are exposed to feline herpes virus, is easy to administer and has a flavor cats love. Viralys powder may be sprinkled over dry food or mixed into a small amount of canned food.

For households with 1 or 2 cats, try Viralys Lysine powder in 100 grams, or Viralys Oral Paste.


Adult cats should receive one rounded scoop twice a day. Kittens can take 1/2 a scoop twice a day, or as recommended by your veterinarian. Each rounded scoop contains approximately 500 mg of L-Lysine.
