Treatment for FCV

Except in cases of severe pneumonia, treatment for feline calicivirus (FCV) is supportive and provided on an outpatient basis.

Make sure the cat eats and drinks enough. Offer foods that smell and taste good to them. If the cat has ulcers in the mouth, give soft foods. Keep the cat's eyes and nose clean and clear of discharge. Make sure the room your cat is staying in is warm, well ventilated, and well lighted.

Pneumonia should be closely monitored for the sudden development of labored, difficult breathing (dyspnea), which may require oxygen therapy. Oxygen therapy is the administration of oxygen through a facemask.

It may be helpful to use a humidifier, or put the cat in a bathroom while the hot shower is running. This helps break up the mucus in the upper airway.

Medications to Treat FCV

Antiviral medications haven't proven beneficial for cats with calicivirus. To treat secondary infections and arthritic pain, the following medications may be prescribed:

  • Antibiotic eye ointments to treat secondary bacterial infections in the eye that can cause conjunctivitis
  • Oral antibiotics to prevent or treat secondary bacterial infections
  • Pain medication for arthritis
  • Vaccination to prevent the progression of the disease
