Breaking news.
This morning I received another H1N1 influenza (swine flu) action alert from the American Veterinary Medical Association (AVMA).
H1N1 update: Cat death in Oregon from presumed 2009 H1N1
November 18, 2009 – The Oregon state public health veterinarian has reported that a pet cat has died from presumed 2009 H1N1 influenza virus infection. The cat was one of 4 cats in the household and became ill approximately one week after a child in the household had a flu-like illness. It developed labored breathing and was presented to a veterinarian on November 4. The cat was not coughing or sneezing but had pneumonia. The cat’s condition deteriorated over the next 3 days, and it died on November 7. Samples were obtained and tested (PCR) positive for the 2009 H1N1 influenza virus. Additional samples were sent to the National Veterinary Services Laboratories (NVSL) for confirmation and are still pending. At this time this is a presumed, not confirmed, case of 2009 H1N1 influenza infection.
The three other cats in the household also became ill with different degrees of sneezing and coughing, but recovered from their illnesses. Samples collected from these cats were negative for the 2009 H1N1 influenza virus.
We continue to update our 2009 H1N1 influenza resources as soon as we receive and verify information. These resources are available at http://www.avma.org/public_health/influenza/new_virus/default.asp. We are also in the process of updating our “Frequently Asked Questions” document for veterinarians to include additional information about sampling and testing procedures, and anticipate the updated document will be posted within the next 24 hours. The document is linked from the H1N1 page or at http://www.avma.org/public_health/influenza/new_virus/new_flu_virus_faq_veterinarians.asp.
The messages to pet owners remain the same.
This is not cause for panic, but underscores the importance of taking pets to a veterinarian if they are showing signs of illness. This is especially important if someone in the household has recently been ill with flu-like symptoms.
Ferret and cat owners should remain vigilant.
To date, all of the sick pets became ill after a person in the household was ill with flu-like symptoms. There is no evidence to suggest that pets have or will spread the virus to humans or other animals.
Proper hygiene and sanitation measures should be followed to limit the spread of the influenza virus.
The web page mentioned in the action alert is a great resource for breaking developments in the matter of swine flu in pets. I recommend that you check it regularly if you are interested in the subject.

Just a week after DVM Newsmagazine (and the Vet Blog) reported that cats and dogs do not appear capable of contracting swine flu (also known as H1N1 influenza), a cat in Iowa has proved the opposite.
Today I received the following action alert from the American Veterinary Medical Association (AVMA).
2009 H1N1 influenza virus confirmed in Iowa cat
November 4, 2009 – A 13-year old cat in Iowa developed signs of a respiratory infection after several people in the household were ill. Preliminary testing was positive for 2009 H1N1 on October 29, and the results were confirmed on November 2. This is the first report of a cat infected with H1N1. The cat has recovered from its illness.
To date, this is the first cat confirmed infected with the 2009 H1N1 virus. Two ferrets, one in Oregon and one in Nebraska, have also recently been confirmed infected with the 2009 H1N1 virus. The Nebraska ferret died, but the Oregon ferret has recovered. To date, there is no evidence that the ferrets or the cat passed the virus to people.
The American Veterinary Medical Association and American Association of Feline Practitioners are reminding pet owners that many viruses can pass between people and animals, so this was not an altogether unexpected event. We are advising pet owners to monitor their pets’ health very closely, no matter what type of animal, and visit a veterinarian if there are any signs of illness.
The good news, of course, is that the cat recovered and that animals have not yet been shown to pass the virus to humans.
I will continue to relay to my readers all of the information I receive on feline or canine H1N1 influenza.

Swine flu, also known as H1N1 influenza, has been dominating the news recently. The viral strain appears set to cause the first influenza pandemic in a generation. Influenza pandemics are big deals. The pandemic of 1918-1920 caused more people to die from flu than from bullets or bombs during World War One.
Influenza viruses are known for infecting multiple species–as the name would imply, swine flu developed in pigs and then spread to people.
This may lead pet owners to wonder: can cats and dogs catch swine flu?
The answer appears to be no. DVM Newsmagazine reports that there is no evidence cats or dogs can contract, carry, spread, or suffer illness from H1N1 influenza.
H1N1 influenza has been isolated from a ferret. Fortunately at this time there is no evidence that ferrets can spread the disease to people.
Although it appears we can rest easy about our cats and dogs catching swine flu, remember that cats are susceptible to an even scarier form of influenza: bird flu (also known as H5N1). Cats contract bird flu by preying upon or being fed raw bird meat. The virus does not appear capable of spreading from cat to cat. That is a good thing, since the fatality rate among cats infected with H5N1 appears to be 100%.
Fortunately, it is easy to protect your cat from H5N1. If you feed your cat commercial or cooked food and keep him indoors, his chances of catching bird flu are nil.
