Understanding Calicivirus in Cats
When it comes to the health of our feline friends, it’s important to be aware of potential illnesses they may face. One such illness is calicivirus, which can affect cats of all ages. Let’s take a closer look at the overview of calicivirus and the severity of the infection.
Overview of Calicivirus
Feline calicivirus (FCV) is a highly contagious virus that can cause mild to severe respiratory infections and oral diseases in cats. It is especially common in shelters and breeding colonies, and often infects young cats (Cornell University College of Veterinary Medicine). The virus can mutate readily, resulting in new strains that may not be fully covered by existing vaccines. This ability to mutate explains why, despite decades of vaccination efforts, outbreaks of calicivirus still occur (Cornell University College of Veterinary Medicine).
Most cats infected with calicivirus recover completely from the infection. However, some rare strains of the virus can be especially deadly, causing severe disease and damage to multiple organs, or even death. Up to 50% of cats affected by these mutant strains may die from the infection. It’s important to monitor your cat’s health closely and seek veterinary care if you notice any signs of illness.
Severity of Infection
The severity of calicivirus infection can vary depending on the specific strain of the virus. The majority of strains cause only mild disease, resulting in symptoms such as sneezing, nasal discharge, and oral ulcers (Cornell University College of Veterinary Medicine). Cats infected with these mild strains usually recover completely with appropriate care and supportive treatment.
However, some cats may develop a more severe form of calicivirus known as FCV-VSD (virulent systemic disease). Cats with FCV-VSD experience more severe symptoms, including a high fever, swelling of the head and legs, crusting sores, and hair loss on the nose, eyes, ears, and footpads. Liver damage may cause the mouth and ears to turn yellowish, and bleeding can occur under the skin and in the gastrointestinal tract. FCV-VSD is fatal in up to 60% of cats that develop the disease (Cornell University College of Veterinary Medicine).
It’s important to note that cats with FCV-VSD typically have a weakened immune system and may be more susceptible to secondary infections. Prompt veterinary care is essential to provide supportive treatment and increase the chances of a positive outcome.
By understanding the overview of calicivirus and the potential severity of the infection, cat owners can take appropriate measures to protect their feline companions. Regular vaccinations and practicing good hygiene are key components of preventing and managing calicivirus in cats.

Symptoms and Effects
Feline calicivirus (FCV) can vary in its presentation and severity of symptoms. The symptoms experienced by infected cats may differ depending on the strain of calicivirus and the individual cat. Understanding the common symptoms and the impact on cats is crucial for early detection and appropriate management of the infection.
Common Symptoms
The symptoms of feline calicivirus infection can manifest in various ways. Common symptoms include:
- Upper respiratory infection, characterized by sneezing and nasal congestion.
- Lethargy and lack of energy.
- Loss of appetite.
- Fever.
- Lameness, which may cause sudden painful limping.
- Gingivitis and stomatitis, leading to inflammation of the gums and mouth ulcers.
- Squinting and conjunctivitis, causing redness and discharge from the eyes.
It’s important to note that symptoms may vary depending on the strain of calicivirus and the individual cat. Young kittens and older cats are more susceptible to severe symptoms, and pregnant cats may experience miscarriage.
Impact on Cats
Feline calicivirus can have a significant impact on the overall health and well-being of infected cats. The infection primarily affects the respiratory system, causing upper respiratory symptoms such as sneezing, nasal congestion, and conjunctivitis. Cats may experience discomfort, reduced appetite, and lethargy due to the infection.
In some cases, calicivirus can lead to more severe symptoms. Certain strains of the virus may cause sudden painful lameness in kittens, while others can result in severe generalized disease. This severe form of the infection may include high fever, severe depression, edema (swelling), jaundice, and multiple organ symptoms. The death rate for this strain can be as high as 67%.
It’s crucial to monitor cats exhibiting symptoms of calicivirus and seek appropriate veterinary care. Early diagnosis and treatment can help manage the symptoms and improve the cat’s overall prognosis. Regular vaccinations and good hygiene practices can significantly reduce the risk of calicivirus infection in cats.

Treatment and Management
When it comes to the treatment and management of calicivirus in cats, the focus is on providing supportive care and addressing any secondary bacterial infections that may arise. Severe cases of calicivirus may require more intensive treatments and hospitalization.
Supportive Care
For cats with uncomplicated calicivirus infections, most can be treated symptomatically at home. Supportive care measures aim to alleviate the symptoms and provide comfort to the cat during the recovery process. The following treatments may be included in the supportive care plan:
- Eye medication to address purulent eye discharge
- Broad-spectrum antibacterial drugs to prevent secondary bacterial infections
- Anti-inflammatory medication to alleviate lameness
- Immune system support for persistent ulcers
- Increased environmental humidification for nasal or airway congestion
It’s important to note that while supportive care can help manage the symptoms, there is currently no direct treatment for a calicivirus infection in cats. The virus will run its course, and most cats recover with time and proper care.
Antibiotics and Intensive Treatments
In some cases, cats with calicivirus may develop secondary bacterial infections that require treatment with antibiotics. Opportunistic bacterial infections commonly occur in cats with calicivirus infections. Antibiotics help combat these infections and prevent further complications.
For severe cases of calicivirus, intensive treatments and hospitalization may be necessary. Cats that are dehydrated, depressed, or severely ill may require intravenous fluid therapy, nutritional support, and other supportive measures. These intensive treatments aim to provide the cat with the necessary care to aid in their recovery.
It’s important to consult with a veterinarian for an accurate diagnosis and appropriate treatment plan for your cat. Veterinary professionals will assess the severity of the infection and tailor the treatment approach accordingly. Treatment options may vary based on the individual needs of the cat.
Remember, early recognition and prompt veterinary care can lead to a good prognosis for cats with calicivirus. Most cats recover following at-home supportive care and appropriate treatments. If you suspect that your cat may have calicivirus, seek veterinary attention for a proper diagnosis and guidance on how to best manage the condition.

Prevention Strategies
Preventing the spread of calicivirus in kittens is of utmost importance to ensure the health and well-being of our feline friends. By implementing proper prevention strategies, we can reduce the risk of infection and minimize the severity of the disease. Two key strategies for preventing calicivirus in cats are vaccination and practicing good hygiene.
Vaccination Importance
Vaccination is a crucial step in protecting cats against calicivirus. While vaccines cannot entirely eliminate the risk of infection, they can significantly reduce the severity of the disease if a cat is exposed. Several combination vaccines are available that provide protection against feline calicivirus (FCV), feline herpesvirus type 1, and feline panleukopenia virus (Cornell University College of Veterinary Medicine). These vaccines can be administered nasally or as an injection.
It is recommended to vaccinate cats when they are young with the FVRCP vaccine, which includes immunization against calicivirus. Kittens should receive several booster shots between 8 and 20 weeks of age, with at least one additional booster a year later. After the initial series, regular boosters should be administered every three years to maintain protection against calicivirus. By following the recommended vaccination schedule, we can significantly reduce the risk and severity of calicivirus infections in cats.
Hygiene Practices
In addition to vaccination, practicing good hygiene is crucial to prevent the spread of calicivirus in cats. It is important to minimize direct contact with infected cats and isolate them from healthy cats to prevent transmission. Strict hygiene measures should be followed, including using separate feeding bowls, litter boxes, and bedding for infected cats. Caregivers should wash their hands carefully before tending to other cats to prevent cross-contamination (WebMD).
Regular cleaning and disinfection of the environment are also essential to eliminate the virus. Calicivirus can survive in the environment for extended periods, so thorough cleaning of surfaces, toys, and other items with appropriate disinfectants is necessary to prevent its spread (VCA Canada). By maintaining a clean and sanitary living environment for our cats, we can help reduce their risk of contracting calicivirus.
By prioritizing vaccination and implementing proper hygiene practices, we can significantly reduce the incidence and severity of calicivirus in kittens and adult cats. However, it is important to remember that no preventive measure is foolproof, and early detection and prompt treatment are key in managing calicivirus infections. If you suspect your cat may be showing signs of calicivirus, consult with a veterinarian for proper diagnosis and guidance.
Spread and Containment
When it comes to calicivirus in kittens, understanding how the virus spreads and the measures to contain its transmission is crucial. Calicivirus is highly contagious among cats and can be transmitted through various means, including direct contact with an infected cat and exposure to contaminated objects. Let’s explore the contagious nature of calicivirus and how it can survive in the environment.
Contagious Nature
Calicivirus is highly contagious, and infected cats can shed the virus in their saliva or secretions from the nose or eyes. When an infected cat sneezes, airborne viral particles can be sprayed several meters through the air, making it easy for the virus to spread to susceptible cats. Additionally, people can also spread the virus to susceptible cats by touching contaminated objects or infected cats. It’s important to note that while calicivirus is primarily a feline disease, it does not pose a significant risk to humans.
Environmental Survival
The survival of calicivirus in the environment is another important aspect to consider. The virus can survive for up to one week in the environment and potentially longer in cool, damp locations. Contaminated objects, such as food bowls, bedding, and toys, can serve as sources of infection for susceptible cats. It’s crucial to regularly clean and disinfect these objects to minimize the risk of transmission.
To prevent the spread of calicivirus, practicing good hygiene is essential. Wash your hands thoroughly after handling an infected cat or any objects that may have come into contact with the virus. Disinfecting surfaces and objects with appropriate cleaners can help in reducing the viral load and preventing transmission. If you have multiple cats, it may be necessary to separate an infected cat from other healthy cats to prevent further spread.
By understanding the contagious nature of calicivirus and taking appropriate measures to contain its spread, you can help protect your furbaby and prevent the transmission of the virus. Vaccination against calicivirus is an important step in preventing infection, and maintaining good hygiene practices can further reduce the risk.

Diagnosis and Prognosis
When it comes to diagnosing and understanding the prognosis of feline calicivirus (FCV) in cats, several methods are used to determine the presence of the virus and assess the potential outcomes.
Diagnosis Methods
Diagnosing calicivirus in cats is typically based on a combination of the cat’s medical history, clinical signs, and potential exposure history to FCV. A definitive diagnosis can be made through a polymerase chain reaction (PCR) test, which looks for FCV DNA in samples taken from the infected cat’s eye, nose, or throat. This test provides accurate results and confirms the presence of the virus (Animal Emergency Care).
It’s important to consult a veterinarian for a proper diagnosis, as they have the expertise and necessary tools to identify FCV accurately. Prompt diagnosis allows for timely treatment and management of the virus, which can positively impact the prognosis.
Prognosis and Recovery
The prognosis for cats infected with calicivirus can vary depending on several factors, including the severity of the infection, the overall health of the cat, and the effectiveness of treatment. Immediate veterinary care plays a crucial role in ensuring a good prognosis for cats with FCV.
Most cats infected with calicivirus recover with proper care and treatment. At-home supportive care, such as keeping the cat’s nose and eyes clean, is often recommended for cats with uncomplicated infections. Treatment may also include the use of eye medication, broad-spectrum antibacterial drugs, anti-inflammatory medication, and immune system support (VCA Hospitals).
For severely ill cats, hospitalization may be necessary. Hospitalization allows for more intensive treatments, such as intravenous fluids and other supportive measures, to be administered (VCA Hospitals). However, it’s important to note that extended hospital stays can result in higher veterinary bills, so it’s advisable to explore available payment options to cover the treatment costs (Animal Emergency Care).
With immediate veterinary care and appropriate treatment, the majority of cats infected with FCV can recover and resume a normal, healthy life. However, it’s essential to understand that infected cats can shed the virus in their bodily secretions for a period of time, and some may develop a carrier state where they continue to shed the virus without showing signs of infection. These carrier cats can pass the infection on to other cats, including newborn kittens, so proper hygiene practices and feline calicivirus prevention strategies are crucial to minimizing the spread of the virus.
If you suspect your cat may be infected with calicivirus, it’s important to seek veterinary care promptly for an accurate diagnosis and appropriate treatment. Early intervention and proper management can greatly improve the prognosis and increase the chances of a full recovery for your feline companion.
