twice Trigger has had a couple of episodes of d&v, though not uncontrolled, and there was a fur ball in the vomit
on the other hand I have a fur ball sausage every two weeks without any d at all
I think you'll know better if it was just a passing thing if there are no more episodes - I hope for your sake there aren't, as it sounds like a rotten homeocoming
(I knew that new smilie would soon be needed
)
