Respiratorias

Feline rhinotracheitis (herpesvirus)

A very common respiratory infection in cats, part of the "cat flu" complex. Caused by herpesvirus and/or calicivirus. Highly contagious between cats.

Moderate🐈 Cats Contagious

Symptoms to watch for

  • Frequent sneezing
  • Nasal and eye discharge
  • Conjunctivitis, watery eyes
  • Ulcers in the mouth or on the tongue (calicivirus)
  • Lethargy and loss of appetite (they cannot smell their food)
  • Fever

Causes

Feline herpesvirus and/or calicivirus. Highly contagious through secretions. Once a cat is infected, herpesvirus stays for life and can reactivate with stress.

Diagnosis

Clinical diagnosis. In complicated cases, specific tests to identify the virus.

Treatment

Supportive care: hydration, cleaning the eyes and nose, stimulating the appetite (tasty, warmed food), and antivirals in severe cases. Relapses are linked to stress.

Prevention

VACCINATION (it is part of the feline trivalent CORE vaccine). Reducing stress and good hygiene in multi-cat households.

When should you see the vet?

See your vet if the cat is not eating (dangerous in cats), has a fever, has difficulty breathing, or if the illness lasts more than a few days.
