just an extremely quick note on the topic of hissing ferrets...
 
ferrets hiss. it's one of their normal weasel noises. mine do it when
playing rough, esp. if they consider an object to be "theirs" and one
of the other weasels gets it, or i take it away...
 
my boy and i refer to it as "Deflating", because, as todd mentions, it
sounds as if they've sprung a leak.
 
what's really amusing is when they make the deflating noise and
flat-ferret at the same time...
 
"Stop letting the air out of the weasels!"
