Did you know that...

  • Feline herpesvirus (FHV-1) is one of the most common causes of respiratory infections and eye problems in cats?
  • FHV-1 is transmitted from cat to cat through: discharge from the nose, eyes or mouth (sneezing, for example) ; litter boxes, water dishes, food, etc.
  • Kittens are often infected by their carrier mother within the first 2 weeks of their life, or most commonly at 5 to 8 weeks of age?
  • FHV-1 is rarely fatal in adult cats but in young kittens, mortality rates can reach more than 30%?

Although FHV-1 cannot be cured, it can be managed safely and effectively. FHV-1 affects cats only. It cannot be passed onto humans or to other species of animals. Improve your cat’s quality of life with Enisyl-F!
