Vetoquinol Viralys Daily L-Lysine Powder for Cats and Kittens – 100g

(Fish Flavored Immune Supplement)

What Is Vetoquinol Viralys L-Lysine Powder for Cats?

Vetoquinol Viralys Powder is a veterinary-formulated oral L-Lysine supplement specifically designed to support feline immune system health, respiratory function, and eye comfort. Ideal for cats and kittens aged 6 weeks and older, this palatable fish & poultry-flavored powder helps manage common symptoms associated with feline herpesvirus (FHV-1) — a major cause of upper respiratory infections and eye inflammation in felines.

The product contains L-Lysine Hydrochloride, an essential amino acid known to inhibit the replication of FHV-1, while also helping to maintain a strong immune response and reduce viral flare-ups in multi-cat households or shelter environments.

What Are the Benefits of Viralys L-Lysine Powder for Cats?

Viralys Powder offers both preventive and supportive care for cats prone to feline respiratory and ocular issues:

Immune System & Respiratory Health

  • Supports a healthy immune response to viral infections
  • Helps manage FHV-1 symptoms such as sneezing, nasal discharge, and conjunctivitis
  • Reduces frequency and severity of flare-ups in stressed or immunocompromised cats

Ocular Comfort

  • Promotes normal eye function by supporting conjunctival and corneal health
  • Assists with reducing eye discharge and inflammation due to viral infections

Highly Palatable Formula

  • Fish & poultry flavor enhances taste and improves compliance, especially in picky eaters
  • Can be easily mixed into wet or dry food without affecting texture

Vet-Recommended L-Lysine Supplement

  • Backed by veterinarians as a daily immune support supplement
  • Ideal for long-term use in adult cats and kittens (6 weeks and older)

Dosage and Administration

Always consult your veterinarian for exact dosage instructions depending on your pet's condition.

  • Kittens under 6 months: 250 mg (approx. ½ scoop) twice daily
  • Cats over 6 months: 500 mg (approx. 1 scoop) twice daily
