Parvo:Feline Panleukopenia

Both feline parvovirus (FPV) and canine parvovirus (CPV) came from an unknown cause. FPV cannot infect dogs. The original CPV strain, CPV-2, could not infect cats. However, the most common field strains now, CPV-2a and CPV-2b can infect dogs as well as cats. CPV-2c is circulating in many parts of the world and can also affect both dogs and cats.

What is Panleukopenia virus (also known as Feline Parvo virus)?

The term "panleukopenia" means a decrease in the number of all white blood cells throughout the body.

What is the Cause and how is it transmitted?

(FPL): Feline panleukopenia is caused by a virus of the parvovirus family. A similar but distant cousin virus to that which is found in canine.

The virus can be transmitted VIA contact with other animals or surfaces such as, water, cloths, feeding bowls, and shoes. It's very easy to transmit this virus.

This virus is present in all excreations, particularly the feces. If you have a multi-cat home, they will all use the same box- which means that the 1 would infect the entire colony of yours.

*Quarantine is always recommended and heavily enforced when introducing any feline to a new pride. We always ask you quarantine for 30 days when bringing in a new member to your family.*

What are the signs of an infected feline?

High Fever

Weight Loss

Diarrhea and Vomiting

Nausea Lack of appetite


Increased hiding


Kittens who are infected during the later stages of in utero development may be born with a neurologic condition called cerebellar hypoplasia which affects the part of the brain responsible for coordination, balance, and movement.

Can panleukopenia be treated?

As for most viral diseases, there's no "specific" for FPL. The only treatment that is available is supportive. Making sure to provide adequate hydration and electrolyte balance (via oral fluids if able to hold them down). Diet plays a huge role in the treatment of this virus.

Other more serious cases can be helped VIA blood transfusion. + Antibiotics may be needed to treat secondary infections.

Kittens born with panleukopenia may have tremors and a wobbly gait, but they can still have a good quality of life with intensive monitoring and care depending on the severity of the condition.

Can you eradicate the virus from your home?

Both FPV and CPV are unenveloped DNA viruses. They are very durable and can persist in the environment for months to years without adequate sanitation. Sanitation is a two-step process that involves physical cleaning followed by chemical disinfection. Additionally, only a few disinfectants—such as bleach derivatives, potassium peroxymonosulfate, and accelerated hydrogen peroxide products—reliably kill parvoviruses. Shelters sometimes elect to leave areas empty after an infectious animal has been present. While repeated cleaning and disinfecting can be helpful, especially in older facilities where the environment may present a challenge to clean, three thorough sanitations in one day is just as effective as three times in three days. If space is at a premium, as it is in most shelters, there is no great benefit to leaving cages empty. One would need to leave the area sitting for months to years!
