Cat Virus

Viral infections are some of the most serious health problems cats can face. A cat virus can spread quickly between animals and in some cases, remain hidden for years before causing illness. Vaccination and early diagnosis are the best ways to protect cats from deadly viruses.
  • Cat viruses can weaken the immune system and shorten lifespan.
  • Common cat viruses include FIP, FIV, and FeLV.
  • Symptoms may be mild at first but worsen over time.
  • Vaccination and regular vet check-ups help prevent infection.

Why Does My Cat Get a Virus?

A cat virus spreads through close contact, shared food bowls, saliva, blood or even from a mother cat to her kittens. Outdoor cats or those in multi-cat households, are at higher risk. Some viruses hide in the body and don’t cause symptoms until months or years later. Because viruses can’t be cured with antibiotics, prevention through vaccination and early care is essential.

Types of Cat Viruses

Feline Immunodeficiency Virus (FIV)

Often compared to HIV in humans, this virus attacks the immune system.

Cats may live for years without signs, but once the immune system weakens, they become prone to infections, gum disease and weight loss. FIV spreads mostly through bites from infected cats.

Feline Leukemia Virus (FeLV)

One of the most common and deadly cat viruses. FeLV weakens immunity, causes anemia and increases the risk of cancers like lymphoma.

It spreads through grooming, sharing bowls, or mother-to-kitten transmission. Many infected cats do not survive long without supportive care.

Feline Infectious Peritonitis (FIP)

A serious disease caused by a mutation of the feline coronavirus. FIP comes in two forms: “wet FIP,” with fluid buildup in the belly or chest, and “dry FIP,” with organ failure and neurological signs. It is almost always fatal, though new treatments are being researched.

Other Viral Infections:

Feline Calicivirus (FCV): Causes mouth ulcers, sneezing, and nasal discharge.

Feline Herpesvirus (FHV): Leads to chronic respiratory infections and eye problems.

 Rabies Viruses: Rare but fatal, spreads through bites from infected animals.

Symptoms of Cat Viruses

Cats with viral infections may show:

Persistent sneezing and nasal discharge

Often seen with herpesvirus or calicivirus. The nose may run and breathing may sound congested.

Mouth ulcers and drooling

Calicivirus often causes painful sores in the mouth, making it hard for cats to eat.

Difficulty breathing or fluid buildup

Seen in wet FIP, where fluid collects in the chest or abdomen, making cats look bloated or breathe heavily.

Eye Problem

Watery, red or swollen eyes are common in cats with viral infections, sometimes with ulcers on the cornea.

Fever and lethargy

Viruses often cause high temperature, leaving cats weak, sleepy or unwilling to play.

Neurological signs

In dry FIP, cats may stumble, lose balance or have seizures as the nervous system is affected.

Cat Virus FAQ

A cat virus is a disease caused by tiny infectious agents that attack a cat’s immune system, organs or respiratory system. Some cat viruses are mild, while others are life-threatening.

Viruses spread through saliva, blood, sneezing, grooming or even from mother to kittens. Outdoor cats and those living in groups are most at risk.

 

Most cat viruses cannot be completely cured, but supportive care and antiviral treatments can manage symptoms and improve quality of life. Vaccination prevents many viral diseases.

 

 

The most common are FIV (feline immunodeficiency virus), FeLV (feline leukemia virus), FIP (feline infectious peritonitis), herpesvirus and calicivirus.

 

Sneezing, runny nose, watery eyes, ulcers, weight loss and lethargy are common. If your cat shows breathing problems, seizures or sudden bloating, seek urgent care.

 

Routine vaccination, keeping cats indoors, and regular vet check-ups are the best protection.
