The vets' logic is: if those coronavirus existed in cats are that deadly and contagious as the strain that we are witnessing now, the virus would have wiped out all cats years ago.

But that doesn't make sense because viruses mutate all the time ---what could have been a fairly benign virus years ago may have converted into something more pathologic ---that's why there are constantly new colds and flus. I guess no one knows where this SARS came from yet ---if it's in some animal host, a wild resorvior ---maybe it's one of those viruses that doesn't make it's natural host very ill but is more dangerous to humans.

Well, if we go along that line of thought, you could be right. As far as we alreay know, AIDS do jumped from apes to human.
