Until September 7th I will give 10 cents to an animal charity for every comment. It is a way to help animal welfare without much effort at no cost. Comments help this website too, which is about animal welfare.

Today I want to talk about Panleuk (Feline Panleukopenia), Parvo (Parvovirus) and Tamiflu (Oseltamivir Phosphate) – please also read the update at the base of the page (Michael).

There are few diseases in the animal world that strike heartbreak and terror into animal lovers as much as panleuk and parvo. Today’s column will be off the beaten path as I will be addressing both cat and dog owners. The two diseases are so alike they are 98% identical, differing in only 2 amino acids. Their symptoms and treatment must be handled quickly or the rate of death exceeds 90%.

Since quite a few of us love both cats and dogs, I hope this article will prove educational without going over the head of those with average intelligence. Research articles tend to do that. And I hope the cat only people will forgive me.

Include me in that group of average intelligence. I’ve said “oh my aching head” at least a dozen times while doing the preliminary research for this article.  I’ll list lots of references as “homework” as there is way too much to get into in one article. 

My primary research into panleuk and parvo is the use of Tamiflu (a neuraminidase inhibitor) to save the life of a pet stricken with this disease that can claim a life only hours after symptoms appear. However, a dog can’t infect a cat and a cat can’t infect a dog.

I’ve never used Tamiflu, which is commonly prescribed for influenza. Not only was it too expensive without insurance, but it only cut the duration of symptoms in humans by one and a half days and the side effects read too much like the flu to even bother with it.  

To save a pet, I would do this. No question about it after researching this article.

One source I read on using Tamiflu for cats and dogs stated the drug should be started before symptoms appear. If an animal has been exposed, begin treatment with the drug immediately. Another article said not to start the drug unless an animal has tested positive using a feline or canine snap parvo test. Personally, if I knew a pet had been exposed, I’d start treatment immediately. Once the disease digs in the Tamiflu won’t help.

I never realized until I began this research just how painful these illnesses are to an animal. When the GI (gastrointestinal) tract is being destroyed and your pet is vomiting and has diarrhea (sometimes bloody), add on lethargy and dehydration and electrolyte imbalances and then sepsis takes over and poisons the blood and kills quickly. Blood and protein leak into the intestines and cause anemia and loss of protein and endotoxins get into the bloodstream causing endotoxemia.  There’s really no way this could NOT be painful.

I can’t stress this enough.. Get the vaccines as a preventive. And should your pet appear ill, do not wait until morning to see if your pet feels better before making a vet visit. Your dog or cat could die before morning.  I’ve learned this the hard way.

Parvo only appeared in the l970’s and it was quickly discovered it was a mutation of the panleuk virus in cats.  Puppies died when the virus infected the rapidly dividing cells of the heart. Vets began using the cat vaccine for panleuk but had limited success due to CPV maternal antibiodies. The disease was more stubborn to fight in dogs than in cats with the vaccine available at the time. We’re fortunate that now dogs have their own parvo vaccine.

There are also two forms of the parvo, and although I haven’t proven this theory in cats as I write this article. I believe this may also be correct in them also with the panleuk since there is the 98% identical markers in the disease..

This is why I stayed so confused when my kittens were sick and dying. There is the intestinal form which causes sepsis. There is also a cardiac form (of parvo) that affects the heart muscle and causes breathing difficulty and mimics the symptoms we see in adults with heart failure. Can cats get the cardiac form? Something tells me they can.

The cardiac form is more likely to be passed on from mother to babies. The mother can build a natural immunity and shake off the disease, sometimes without symptoms. That’s what I believe my Marley did. You should have seen the black diarrhea mess the vet cut away from Marley’s anal area. My vet was fairly certain she had been infected with panleuk and recovered. She was fortunate to survive this. Marley lived and all her her Whineybutt babies save one died. Midnight is slowly recovering and still grieving the loss of his brothers and sisters.

This is the link (Wiki article) that has gotten me so excited. So much information packed into one article. Since puppies can get the cardiac parvo, has anyone done any research into whether kittens can get the cardiac form also? This fits to a tee how my kittens died

The cardiac form is often the form that kills a family pet overnight with no symptoms. All you may notice is a little difficulty breathing and lethargy and by morning your pet is dead.

Can anyone out there back me up that this occurs in felines as well as canines since the similarity of the diseases is so close to 100%? The research is saying only young puppies usually get the cardiac form.

Now for more information on how the Tamiflu works to stop parvo and panleuk. These findings aren’t from an actual scientific study; only from vets and shelters who began experimenting in their own practices to stop the growth of neuraminidase.  

It isn’t fully understood whether parvo and panleuk need neuraminidase to cause the bacteria to kill our pets. But Tamiflu can stop whatever it is in its tracks. Here’s the link to a very complicated article I’d suggest you study as it explains how the disease functions. The truth might surprise you. There is hope if you act quickly. I would like to warn this information is very confusing. Here is a link from a vet who uses Tamiflu to treat feline distemper.

Tamiflu is not a substitute for conventional treatment.  IV,’s, dehydration fluids such as Pedialyte and antibiotics are still needed. A vitamin B-12 shot may be needed to help with the anemia. 

The main problem in the past was cost. Only rich people could afford to save their sick pets. When this research article was written back in 2008 they figured the cost at around $40 per dog. 

Of course the weight difference in dogs and cats must be taken into consideration. I found this excellent article written by someone who pulled her kitten through panleuk and she kept a diary including dosage amounts, side effects, etc.

Tamiflu requires a prescription and doesn’t have a long shelf life. To use it on a pet and it’s purchased through a pharmacy, please use a compounding pharmacy. These aren’t as difficult to find as you might think. Most medicine we use today began as a compounded drug. A veterinarian can also mix Tamiflu as an oral suspension and advise dosage instructions.

This is HUGE, readers. I don’t have any idea how many shelters and vet practices know about this. None of my vets ever even mentioned Tamiflu as a treatment. If we must educate our vets to these new treatments, then we need to do that. We are an animals only voice when it’s sick!

When the cost to treat an exposed cat or dog is less than the cost to euthanize, this could become standard practice at shelters.  It would save thousands of lives each year. Not only those with the disease, but the stress caused to shelter workers who must euthanize cats who have done nothing wrong except be in the room with a sick cat.

In the private sector it would mean kittens and puppies could be treated low cost at home if good care by a family member was available.  After a vet visit first since this is very complicated and your pets life depends on it.

Yes, I realize Tamiflu has it’s down side like every other drug out there. But when you’re looking at a survival rate at less than 10%, you may have to take the risk and use the drug.

Veterinarians, are any of you using Tamiflu in your practice to treat parvo and panluek. Do any of you (physicians or not) have any more links we might find helpful? And the question I’d REALLY love to know the answer to. How many vets out thee have never even heard of using Tamiflu?

My greatest fear of these diseases in dealing with vets who either don’t know of the excellent results achieved by the drug or are too “old school” to try something new. Not even ONCE did I hear the word Tamiflu used as a treatment option. Things could have ended a lot differently if I had.

Anything I’ve missed? Comments and especially experience in working with Tamiflu would be most helpful.

Update: this is more than 10 years later (Oct 2020) as the date on the article is wrong. It was written before 2012. Anyway, I thought I’d update it with a successful treatment for panleuk by Jane K Rice which you can read in it is entirety by clicking on this link. It incorporates tamiflu. Here is the outline (I have decided that I can publish it here because there is a freed download of the page in question and therefore it is publishable under a creative commons license:

Treatment outline

1) Identify FPV with parvo test or WBC count and symptoms. Parvo test any severely sick or deceased kitten or cat with unknown sudden cause of death. Isolate sick cats.

2) Start Neupogen, and give on days 1, 2, and 3 (optional), skip a day and resume on days 4 or 5.

3) Start two broad spectrum antibiotics, Baytril and penicillin G, typically.

4) If kitten is under about 2 lbs, start Tamiflu. (Or if a lot of bloody stool at any age); as alternative, start metronidazole if feline is over about 3 months old.

5) Start Vitamin B12 or highly diluted Vitamin B-complex.

6) Give fluids, anti-vomit meds, and feed small amounts of A/D Hills diet.

7) Keep track of temperature throughout. Keep at or below 103.5 F, but a modest elevated temperature is good.

8) Continue with supportive therapy and antibiotics for full course of treatment. (Typically 7 days, or 3 days past all symptom resolution, but at least a minimum of 5 days)

9) Cat will “break though” pretty suddenly and just get up and be very hungry and want to eat and drink, usually 3-5 days after symptoms appear.

10) Closely watch and slowly remove supportive therapies as cat is able to do for him/herself. Feed often during this time period.

11) Keep cat isolated for 2.5 to 3 weeks after recovery, bathe coat, and decontaminate environment.is

  1. comment from Jk Rice. two changes to 2017 panleuk paper.
    1) we no.longer bathe. you can do.lye dyp without rinse, leave 5 min and dry with.warm towels to prevent shivering. this will supresss ringworm.
    2).we.give full series.of vaccines every 4 week until 16.weeks of age
    we count the disease as the equivalent of the first vaccine
    3)..the 1 yr booster panleuk.vaccine.is VERY CRITICL. NEVER miss the.one year booster vaccine.
