What is Feline Upper Respiratory Infection?

Feline Upper Respiratory Infection (URI) is a common and highly contagious illness in cats, often referred to as “cat flu.” It is caused by a variety of viruses and bacteria that affect the upper respiratory tract. Common pathogens include feline herpesvirus (FHV), feline calicivirus (FCV), and Chlamydia felis.

Symptoms

The symptoms of URI can vary but typically include:

  • Sneezing: Frequent sneezing is common.
  • Nasal Discharge: Clear, yellow, or green mucus.
  • Eye Discharge: Watery or pus-like discharge from the eyes.
  • Coughing: May be accompanied by a raspy or hoarse sound.
  • Loss of Appetite: Decreased interest in food.
  • Fever: Elevated body temperature.
  • Lethargy: Reduced activity levels.

Causes

URI is primarily caused by infectious agents such as:

  • Feline Herpesvirus (FHV): Causes severe eye and nasal discharge.
  • Feline Calicivirus (FCV): Can lead to oral ulcers and lameness.
  • Chlamydia felis: Often causes conjunctivitis (eye inflammation).
These pathogens are spread through direct contact with an infected cat or contaminated environments and objects.

Diagnosis

A thorough physical examination by a veterinarian is essential for diagnosing URI. Diagnostic tests may include:

  • Blood Tests: To check for infections or underlying conditions.
  • Swabs: Samples from the nose or throat for laboratory analysis.
  • Imaging: X-rays or ultrasound if complications are suspected.

Treatment

Treatment for URI usually involves supportive care and may include:

  • Antibiotics: To treat secondary bacterial infections.
  • Antiviral Medications: In severe cases, to combat viral infections.
  • Nasal Decongestants: To relieve congestion and improve breathing.
  • Fluids: To prevent dehydration and support overall health.
  • Nutritional Support: To ensure proper nutrition during illness.

Prevention

Preventing URI involves:

  • Vaccination: Keeping your cat’s vaccinations up-to-date.
  • Hygiene: Regularly cleaning feeding dishes and litter boxes.
  • Isolation: Keeping infected cats away from healthy ones.
