Washington D.C. - The U.S. Department of Agriculture says pigs in a commercial herd in Indiana have tested positive for the swine flu virus. This is the first case of swine flu in a commercial herd in the United States.  The USDA says the pigs as well as the people caring for the pigs have recovered. The sample was collected in late October. Last month, tests confirmed several show pigs at the Minnesota State Fair contracted the virus.

H1N1 has also been confirmed in a cat treated at the Iowa State University College of Veterinary Medicine. It's the first known case of the virus to be diagnosed in a cat.  Vets have also confirmed H1N1 in two ferrets, one in Oregon and the other in Nebraska.

The cat was treated in Ames and is recovering. The veterinarian who treated the cat says two of the three people in the same house had flu-like symptoms before the cat became ill. The case was confirmed at both Iowa State and the U.S. Department of Agriculture.

Sponseller says the flu is known to spread from humans to pets, but this is the first case of swine flu to spread to a cat.
