Feline Herpes Virus 1 (FHV-1 or Feline Rhinotracheitis Virus) is a viral infection that causes upper respiratory symptoms and conjunctivitis in cats. Cat herpes symptoms can include: sneezing, nasal discharge, eye discharge, nasal congestion, and conjunctivitis. The virus is spread through an infected cat’s saliva, nasal discharge or eye discharge. Feline herpesvirus is highly contagious, especially in shelters and multi-cat households. An infected cat will usually show symptoms for a few weeks at a time and during other periods, the virus lays dormant in the cat’s body. Supplements for herpes in cats along with a low inflammatory diet can reduce flareups and symptoms.
