Chronic Herpes Virus in Cats

The feline herpes virus is one of the main culprits of ocular and respiratory infections in cats. A herpes infection is, by its very definition, a chronic condition. Once cats are infected with herpes, they will struggle against outbreaks for the rest of their lives. Learn to recognize the symptoms of the feline herpes virus and how to treat the outbreaks.

  1. Description

    • Feline herpes virus is highly contagious.

      The herpes virus is also called feline rhinotracheitis virus and FHV-1. The herpes virus is one of the most common causes of feline respiratory infections. Like its similar counterpart, the human herpes virus, the feline herpes virus causes chronic health issues. Cats who contract the herpes virus are carriers for life.

    Development of Symptoms

    • Many cats are carriers of the herpes virus and never exhibit symptoms. Outbreaks of symptoms are generally caused by stress, such as a move to a new home, introduction of a new pet, other injury or illness. Any time the cat's immune system is stressed or compromised, the herpes virus may take the opportunity to manifest.

    Symptom: Eyes

    • The most classic symptoms of feline herpes virus affect the eyes of the cat. Cats with herpes outbreaks will develop conjunctivitis, including weepy eyes and significant discharge. In many cases, corneal ulcers will also develop on the eyes. If the ulcers are left untreated, scar tissue will form over the site of the ulcers, permanently affecting the vision of the cat.

    Symptoms: Respiratory System

    • Herpes outbreaks can be especially dangerous for kittens who stop drinking and eating.

      During herpes outbreaks, the cat's respiratory system will almost always be affected. Cats will have runny noses, congestion and sneezing. In some cases, the congestion can affect the cat's appetite, so dehydration and complications from a lack of calories can become a concern. Cats who stop eating and drinking due to a herpes outbreak should immediately be seen by a veterinarian.

    Treatment

    • Unfortunately, herpes virus infections are permanent. The goal of treatment is to limit the outbreaks and manage symptoms that do arise. Oral and ocular antiviral medications are available through veterinary prescriptions. Adding lysine to the regular diet can also help limit the replication of the virus. When symptoms do appear, oral and ocular antibiotics may be necessary as well as supportive care for respiratory complications.
