Well, my roommate just emailed me...She took him to the vet this afternoon. They bandaged it up but they told her if may take up to 5 days to know whether or not he needs surgery....? I guess this tail thing is pretty serious and very hard to heal.
She doesn't tell me alot and she will never incriminate herself so I never really know the whole story....
I feel bad for Jack and hope it's nothing serious.

She's lucky it wasn't Duncan's tail....
