Feline Panleukopenia Virus (FPV)

Feline panleukopenia (FPV), also known as feline distemper, is a viral infection among cats that is caused by parvovirus. Similar to parvovirus, it is extremely resilient and can survive on nearly any surface and for extensive periods of time. FPV is highly contagious and often fatal. While it is not contagious for humans or dogs, ferrets can spread the disease to and can obtain the disease from cats. Panleukopenia is spread through contact with an infected animal’s bodily waste, body fluid, bed, or dishes. Pet owners can also carry the disease on their clothing and shoes.

FPV harms a cat by depleting their white blood cell count, leaving them susceptible to secondary infection; and attacks the lining of their gastrointestinal tract, causing internal inflammation, pain, and bleeding. The disease is entirely preventable with regular vaccination. Mothering cats can also spread the virus to their unborn kittens; therefore, it is highly recommended that pregnant cats are routinely vaccinated to prevent spreading FPV to their offspring.

If you have any questions about vaccination scheduling or would like to schedule a booster vaccine for your cat, contact our office today!

Symptoms of feline panleukopenia virus 

  • Abdominal pain
  • Bloody diarrhea
  • Depression
  • Fever
  • Lethargy 
  • Loss of appetite
  • Severe dehydration
  • Tail-biting
  • Vomiting
  • Weight loss

If your cat exhibits any of the aforementioned symptoms, please contact our office immediately, as it may indicate a life-threatening illness.

How is feline panleukopenia treated?

Upon bringing your pet in, the veterinarian will first perform a thorough physical exam to properly diagnose FPV. A Complete Blood Cell Count test will be completed, along with testing on a fecal specimen (when possible). The blood sample will indicate a drop in white blood cell count, suggesting panleukopenia, while the specimen can register traces of the FPV virus.

Because there is not a cure for panleukopenia, treatment is focused on supporting the side effects until the virus subsides, much like treating a human cold. Administering fluids to prevent dehydration, inoculating antibiotics to prevent systemic infection, and providing supplementary medications to curb diarrhea and vomiting are all possible therapies. In most cases, successful veterinary care of FPV patients involves 24/7 in-patient care.

Remember, FPV can be prevented with a proper vaccination regimen. Please consider pet vaccination before it is too late.

Here's a vet that still cares.
Just wanted to say I love Dr. Petcu's staff and his compassionate , caring way of taking care of my dogs.The staff is not only friendly and professional ,they know who you are when you arrive ,and they actually love animals. Is the first Animal Hospital that my dogs are at ease and feel comfortable.The place is very clean and the reception area very elegant and inviting. Exquisite services and Dr. Petcu always take his time to explain the disease and options and still finds time to play with my dogs. He's always treated both his animal and human patients with compassion and dignity,and would never recommend procedures unless he truly feels your pet will benefit from it. One of the vets that cares for your pet. The prices are reasonable and the services exceed all expectations. I Highly recommend Dr.Petcu and his hospital.

Western Animal Hospital AMAZING! Western Animal Hospital is the best place in the valley .The staff is professional, friendly, caring and accommodating. The hospital is very clean and upscale. The customer service and the provided services are outstanding.Dr. Petcu is one of the most professional veterinarians that i have ever met in my 25 years of pet parenting. I drive across the valley just to see him( i live in Anthem) .He really cares about his animal patients and it shows in every visits . He is very knowledgeable , compassionate, friendly and always takes the time to answer any question i have and explaining in detail any situation we are dealing with. I had my share of visits to many animal hospitals in the valley but none of them had the last technology as Western - digital X-ray ( they send you home with a cd for you x-ray records ) every room has a computer monitor where the x-ray shows and Dr. Petcu can review with me every detail of it. Also they have the laser surgery and digital dental x-ray. Dr. petcu is one of the most
courteous and pleasant Vets I have ever met. The prices are more than reasonable and also they try to accommodate everybody. I cannot recommend them enough. You can rest easy knowing your pets are in their care.I STRONGLY RECOMMEND THIS HOSPITAL - THEY HAVE A CUSTOMER FOR LIFE IN ME! very good !

.the best vet I met !! Pam M. 5 Western Animal Hospital - we are bringing our pets to Dr Petcu for 8 years. He was always helpful, many times we did not have the funds to treat our pets but he was fine with us paying when we had the money. He saved our cats in many instances and all I have to say is that I greatly reccomend Western Animal Hospital for any responsable pet owner .
