What is Calicivirus in Cats?

Feline calicivirus (FCV) is a highly contagious viral infection that primarily affects a cat's respiratory system, mouth, and occasionally other organs. It’s a leading cause of upper respiratory infections in cats, affecting both wild and domestic cats globally.

Key Facts:

• The virus is resilient, surviving in the environment for up to a month.
• It’s particularly common in shelters, catteries, and multi-cat households.
• There are different strains, and symptoms can range from mild to severe depending on the variant.

How Serious is Calicivirus in Cats?

The seriousness of calicivirus varies. In many cases, calicivirus symptoms are mild and can be managed effectively. However, certain strains can cause severe symptoms, including pneumonia and potentially fatal complications, especially in kittens, elderly cats, or cats with weakened immune systems. Vaccination is crucial to reduce the risk of severe illness.

Symptoms of Calicivirus

Calicivirus symptoms are mainly respiratory but can affect other areas of the body as well.

Common Symptoms Include:

• Sneezing and nasal discharge
• Ulcers on the tongue, gums, and palate
• Fever
• Loss of appetite
• Eye discharge and conjunctivitis
• Limping or joint pain in some cases

In severe cases, symptoms may escalate to pneumonia, especially if other infections or viruses are also present.

How is Calicivirus Transmitted?

Calicivirus spreads through direct contact with infected cats or by exposure to contaminated objects. For example, food dishes, bedding, and toys can easily transfer the virus between cats. It's essential to thoroughly clean and disinfect any areas or objects an infected cat has come into contact with.

Prevention Tips:

• Isolate new or infected cats from others until they’ve been tested or recovered.
• Wash and disinfect shared items regularly.
• Ensure your cat is vaccinated to protect them against common strains.

Can Humans Get Calicivirus?

No, feline calicivirus does not infect humans. It is species-specific, meaning it only affects cats. However, humans can act as carriers by bringing the virus home on their hands, clothing, or shoes after handling infected animals or contaminated surfaces.

Is Calicivirus the Same as Cat Flu?

Yes, calicivirus is a major component of what is commonly referred to as "cat flu." Alongside the feline herpesvirus (FHV), calicivirus is one of the most common causes of respiratory infections in cats. Together, these viruses contribute to the symptoms associated with cat flu, including sneezing, coughing, and discharge from the eyes and nose.

Treating and Managing Calicivirus

There is no cure for calicivirus, but supportive care can manage the symptoms and help your cat recover. Treatment usually focuses on alleviating symptoms and preventing secondary infections.

Common Treatments:

• Antibiotics for secondary bacterial infections
• Antiviral medications for severe cases, though they are not always required
• Fluid therapy if your cat is dehydrated
• Pain relief for mouth ulcers or limping symptoms
• Steam therapy or humidifiers to help with congestion

Supportive Care at Home:

• Ensure your cat is eating and drinking enough; offer softer food to ease discomfort from mouth ulcers.
• Gently clean any nasal or eye discharge.
• Monitor your cat’s breathing and seek veterinary care if you notice any worsening symptoms.

Can Cats Live a Long Life with Calicivirus?

Yes, most cats with calicivirus recover and can live long, happy lives. Cats that experience a severe infection may have occasional relapses or remain carriers of the virus, which means they could intermittently shed the virus and show mild symptoms. It’s crucial to maintain regular vet checkups and provide a stress-free environment, especially in multi-cat households, to prevent flare-ups.

What Kills Calicivirus?

Calicivirus is resilient, but it can be eliminated from surfaces with specific disinfectants.

Effective Disinfectants:

• Bleach (1:32 dilution) is effective for killing calicivirus on hard surfaces. Allow the solution to sit on surfaces for 10-15 minutes before rinsing.
• Specialized veterinary disinfectants: Products designed for animal shelters and clinics are often highly effective.
• Sunlight and ventilation: While not a primary means of disinfection, proper ventilation and sunlight exposure can help reduce the virus’s presence in the environment.
