Big Acoustic Kitty is home and very happy about it, thankyouverymuch. It's a long story and we've got a busy day ahead of us (including a trip to our regular vet for yet more blood work) but the gist of it is that they're pretty sure his diabetes has gone into remission and this pancreatitis is on the way out, and it was all his medicine that caused the problem.
(And I've discovered that "mother guilt" can attack kitty-mamas as well as human ones, since I feel awful about being the one who gave him the medicine that morning that set him off.)
So ... more later, after things settle down. But for right now, BAK is home and resting and enjoying lots of skritches and cuddles. And stern instructions to never scare me like that again!
Many, many thanks to everyone who send prayers and good thoughts our way. They were much appreciated, and obviously worked very well!!!
