Whew I'm very glad that the University is cool with you calling them if concerned and the vet (yours that was in surgery) sounds like he is back in the game and Flynn will come through this hopefully fine and dandy. You might be a bit worse for wear, keep the wine bottles handy.

What Ken said, I think is very reassuring, and he has been down the road before.

Take care, hugs,
Sharlene and Molly Muffin
