The vet just called and said that Stella is in recovery from her surgery, and is on a continuous morphine drip through the night, but should be just fine. The first two weeks of her recovery are probably bound to be the hardest - she's not supposed to use stairs, and nothing but trips to the bathroom for the outside world. There's also going to be a long period of time where she can't be off-leash, but she's been really good about it so far, and I've got high hopes.
Thanks to everyone who contributed to the Stella fund. The amazing generosity of people - even those she has barked at/left hair on/rooted through their garbage astounds me. Thanks also to all my friends for being there to listen to me and my drama-queen self, who let me get all teary, and who sent me music. All yall rock.
