According to the AVMA Web site, it's unlikely for cats or dogs to contract the H1N1 virus. Like most flu viruses, it appears to be transmitted from person to person. However, the AVMA reported in October that a USDA laboratory confirmed the H1N1 infection in a ferret and a pig. So far there are no reports of the virus being transmitted from animal to animal or from animals to a person. Again, in the cases of infected animals, it's believed the animals contracted the virus from their owners. If people contract the H1N1 virus, taking the necessary precautions to protect pets will help ensure they remain virus-free.
