Vetoquinol Viralys Gel

Viralys is a widely recognized L-Lysine supplement designed specifically for feline health, particularly to support natural respiratory defenses and eye health in cats. The product is marketed as a highly palatable gel that can be administered directly or mixed with food to manage conditions related to the feline herpes virus.

The brand belongs to Vetoquinol, a prominent global player in the animal health industry with a history dating back to 1933. While the company has deep French roots, its manufacturing operations for supplements like Viralys are often based in Canada (specifically through their Vetoquinol N.-A. facilities) to serve the North American market. Vetoquinol remains an independent, family-controlled company, maintaining its position as one of the largest veterinary pharmaceutical companies in the world without being absorbed by larger conglomerate peers.
