The American Veterinary Medical Association reports that three cats in the United States are dead from H1N1. The third cat, a 12 year old domestic shorthair from Pennsylvania, developed respiratory illness on November 3, 2009 after four family members in the home were ill with flu-like symptoms. The cat was reportedly lethargic, suffering from loss of appetite and difficulty breathing. X-rays revealed pneumonia. The cat was treated with antibiotics, but the pneumonia worsened and died on November 6, 2009. Nasal swabs collected on November 6 were negative for the 2009 H1N1 flu virus, but samples collected at necropsy tested positive for the virus on November 14. The NVSL conducted additional testing and confirmed the presence of 2009 H1N1 influenza on November 27, 2009. As the situation develops, the AVMA is updating their resources, including FAQs for veterinarians and for pet owners. The AVMA says that "this is not cause for panic and extreme measures." So far, all of the pets infected with the 2009 H1N1 virus were infected from their ill owners. The AVMA experts say that if you're feeling ill and have flu-like symptoms, limit your contact with your pets (and other people, for that matter) until you are feeling better. And if your pet is showing signs of illness, contact your veterinarian.
