Qinghai-like H5N1 from Domestic Cats, Northern Iraq
Significant on many levels: cats are second only to primates in their similarity to human respiratory and receptor systems (pigs are a close third apparently, I always thought they were more similar -- live and learn); there are 60 million feral cats in the US and 50 million "outside" domestic cats and all hunt/eat wild birds; cat-to-cat infection is extremely efficient.
Obviously there will be implications if you have an "outside" cat and live near a flyway after H5N1 spreads to N. Am.
