Parvovirus in cats, also known as feline panleukopenia virus and feline distemper, is a highly contagious virus. The disease affects cats of all ages but is particularly dangerous for kittens.
It belongs to the parvovirus family, the same group of viruses that includes canine parvovirus. However, it is species-specific and does not spread from cats to dogs or humans.
This virus attacks rapidly dividing cells in a cat’s body, targeting areas like the bone marrow, intestines, and lymphatic system.
Because of its impact on these critical systems, it often causes severe gastrointestinal issues, a weakened immune system, and, in some cases, neurological damage in kittens still developing in the womb.
Pet owners must know about parvo in cats–its symptoms, causes, and how to prevent this life-threatening virus from harming the lives of pets.
Causes and Transmission of Parvo in Cats
Parvo in cats is caused by the feline panleukopenia virus, and many factors come into play regarding how cats contract this deadly disease. Here are the causes of parvovirus in cats.
Direct Contact with Infected Cats
Infected cats shed the virus in massive amounts through their bodily fluids, including saliva, urine, feces, and vomit.
Any healthy cat that comes into direct contact with these fluids can contract the virus. Grooming, nose-to-nose contact, or even playing can be enough to spread the infection.
Types of Cats Vulnerable to Parvo
Kittens’ immune systems are still underdeveloped, especially those under 12 weeks old. Because they are still young, they aren’t able to take vaccinations to protect them from the virus.
Unvaccinated cats have high risks of contracting parvo. Vaccination against parvovirus in cats is the most effective way to prevent the disease. The virus itself cannot be killed, which means it will be extremely hard to treat your cat.
Pregnant cats can transmit the virus to their young before giving birth. FPV can cross the placenta and harm developing kittens, often causing severe birth defects, miscarriage, and neurological issues.
Malnourished or sick cats have weaker immune systems, making it harder for them to fight off the virus. This makes them have a weakened defense against the virus.
Contaminated Objects
Parvo in cats can survive on items like food bowls, litter boxes, bedding, and even toys. Cats don’t have to interact with an infected animal to catch the virus. Just by sharing the same space or using contaminated items, they are at risk.
Flea Infestations
Fleas can be carriers of parvovirus when they feed off an infected cat. When the parvo-infected flea moves to your cat, your pet may contract the disease.
A flea infestation may increase the chances of your cat contracting parvo because this can weaken your cat’s immune system, making it more susceptible to infections.
High-Risk Environments
This virus is incredibly tough, capable of surviving outside a host for up to a year in some conditions. It thrives on surfaces in homes, shelters, and outdoor spaces.
Even seemingly clean environments can harbor FPV if they haven’t been disinfected properly with specialized cleaning agents like bleach solutions. Some examples of high-risk environments include:
Animal Shelters
Overcrowded conditions in cat shelters are a common sight to see. Because of this, the chance for cats to contract parvovirus is high, especially if they are all kept in a single area.
Outdoor Areas
Most strays and feral cats carry dangerous diseases because of the neglect they have faced. Your pet that loves to roam can interact with these outdoor cats, increasing the risk of parvovirus.
Multi-Cat Households
Homes with multiple cats, especially if one is unvaccinated or has been exposed to the outdoors, are at higher risk.
Veterinary Clinics
A lot of cats visit the vet clinic for a checkup and treatment. The virus can linger on surfaces and equipment in vet clinics that don’t practice proper sanitization between patients.
Boarding Facilities
Cat boarding facilities house a lot of cats from different backgrounds. This means the chance for the virus to spread from cat to cat or through the items and bedding they use is high.
Human Carriers
Humans can’t contract parvo from cats, but they can unknowingly be carriers of the virus. Shoes, clothing, and hands that have come into contact with contaminated surfaces or infected cats can bring the virus into your home.
Parvovirus Warning Signs in Cats
It’s difficult to notice immediately if your cat has parvovirus because the symptoms of this disease can be similar to other illnesses. However, it’s important to know that these signs may already be the onset of parvo in your cat.
Lethargy and Weakness
Extreme fatigue and lethargy are some of the cats' first signs of parvovirus. You’ll notice your cat to be less active, and it would prefer lying down more often. Difficulty walking and getting comfortable are also signs you’ll notice.
Loss of Appetite
Infected cats often show a complete loss of interest in food and water. Because of this, secondary symptoms might appear, such as weight loss and dehydration. The lack of nutrition will lead to more problems down the road.
Vomiting
Persistent vomiting is a common symptom of parvo, ranging from clear liquid to yellow or foamy bile. Observing the type and frequency of your cat’s vomit will help vets diagnose your cat’s condition.
Diarrhea
Diarrhea can also be observed in cats with parvovirus. In severe cases, blood will be present, indicating damage inside the body, particularly the intestines. Persistent diarrhea can cause severe dehydration, making it harder for your cat to recover.
Fever
During the initial stages or parvo in cats, high fever can develop as that cat’s body attempts to fight off the virus. Fever usually doesn’t appear during the initial stage of the infection.
Abdominal Pain
Parvovirus affects the intestines, leading to gastrointestinal issues such as inflammation and irritation. Cats with abdominal pain may display an unrelaxed posture and cry out when their abdomen is touched.
Diagnosing Parvo in Cats
Diagnosing parvovirus involves various steps and diagnostic methods. Vets need to conduct different tests since the symptoms of parvo in cats can be similar to FIV (feline immunodeficiency virus) or FeLV (feline leukemia virus).
To give you an overview of what to expect, here are the common techniques vets use to detect parvo in cats.
Physical Exam
Vets will first perform a physical examination of our cat to get an initial assessment of your cat’s condition. The vet will determine the next diagnostic tests your cat needs depending on the clinical signs observed.
Fecal ELISA Test
This quick test detects the presence of parvo in your cat’s stool. While highly effective, it may sometimes yield false negatives if the virus is not yet being shed by your cat, which is usually during the early stages of parvo.
Complete Blood Count
Parvo attacks the cat’s bone marrow, producing a low white blood cell count. A CBC (complete blood count) will be conducted to help determine the low levels of white blood cells, which can confirm that your cat has parvo.
Polymerase Chain Reaction (PCR) Test
The PCR test detects cat parvovirus in feces or blood samples. This test is extremely sensitive, meaning it can identify even tiny traces of FPV, making it highly reliable.
Imaging Tests
In some cases, vets may recommend X-rays or ultrasounds to check for intestinal and other gastrointestinal damage caused by the virus. This enables the vets to determine the areas affected by the inflammation and irritation.
Feline Parvovirus Treatment Options
While there is no definite cure for parvovirus in cats, veterinarians use various treatment methods to help manage the symptoms and prevent complications.
Cats will be given supportive care treatments such as fluid therapy and nutritional support. IV fluids are vital for parvo patients to avoid dehydration and its complications.
Nutritional support is also given to cats infected with parvovirus to prevent malnutrition and worsening its condition. Medications may also be given by the vet to control vomiting and diarrhea. These can help your cat recover from the effects of the disease.
Other medications, such as antibiotics, can help prevent secondary infections. Because of your cat’s weakened immune system, complications can arise and get in the way of its recovery.
Monitoring Your Cat’s Recovery from Parvovirus
Parvo can be fatal, so your cat needs to be hospitalized, where it can be treated and monitored by expert vets and qualified staff. Recovery time may vary, but this usually lasts for a few weeks. Kittens and ill cats may need extended vet care, while healthier cats may recover more quickly.
Once your cat is cleared to go home, continue home care for a full recovery. This includes providing a quiet, stress-free environment, helping with hydration, and following the instructions of your vet regarding medications.
Your vet may also schedule a follow-up vet visit to check on the status of your pet’s recovery. It’s also advisable to isolate your pet for at least six weeks after recovery since your cat may still shed the virus, which can affect other cats in your home and the community.
The Importance of Vaccination for Parvovirus in Cats
Cat vaccination is highly effective in preventing feline parvovirus. It’s essential to find the best way to protect your cats from the dangerous disease. With a regular vaccination schedule, your cats will have a significantly reduced chance of contracting the virus.
Kittens must get vaccinated as soon as their bodies are ready, as the virus can easily target young and immuno-compromised cats. Early protection is always a good practice.
Additionally, vaccination helps prevent the spread of the virus around the cat community. This makes it safer for every cat in grooming salons, boarding facilities, and cat shelters. Overall, vaccinating against parvovirus is the best way to protect your feline companion.
Conclusion
Parvo in cats can easily spread from a single infected cat in the community. Because of this, you must do your part as a responsible cat owner to vaccinate your pet. This will help protect your cat’s health and prevent the spread of the dangerous virus to nearby cats.
Remember that parvovirus can thrive on any surface, and people can also be carriers. It’s also difficult to eliminate this virus as it can survive long without a host. This is why keeping your cat’s vaccination updated is the best way to keep it safe and live a disease-free life.
