Unexpected unidentified mammalian AI hosts for H5N1 proved to be the domesticated cat and pikas (in China). Perhaps H7N9 will find a home in them also.
H5N1 avian influenza in domestic cats
28 February 2006
Authorities in Germany have today announced detection of H5N1 avian influenza in a domestic cat. The cat was found dead over the weekend on the northern island of Ruegen.....

Abstract
During the 2003 to 2004 outbreak of avian influenza A (H5N1) virus in Asia, there were anecdotal reports of fatal infection in domestic cats, although this species is considered resistant to influenza. We experimentally inoculated cats with H5N1 virus intratracheally and by feeding them virus-infected chickens. The cats excreted virus, developed severe diffuse alveolar damage, and transmitted virus to sentinel cats. These results show that domestic cats are at risk of disease or death from H5N1 virus, can be infected by horizontal transmission, and may play a role in the epidemiology of this virus.

New Study Finds Wild Pikas Are Natural Mammalian Hosts To H5N1 Avian Influenza Virus
Aug. 25, 2009 ? For the first time a new study suggests that when exposed in their natural ecosystem, wild pikas (a species closely related to rabbits) are mammalian hosts of H5N1 subtype avian influenza viruses and may also be a source of transmission to domestic mammals and humans.
The researchers from China report their findings in the September 2009 issue of the Journal of Virology.

"Our findings first demonstrate that wild pikas are mammalian hosts exposed to H5N1 subtype avian influenza viruses in the natural ecosystem and also imply a potential transmission of highly pathogenic avian influenza virus from wild mammals into domestic mammalian hosts and humans," say the researchers.
