I just called, they just got done with the surgery! It's only quarter after 3pm here!
The receptionist spoke with the vet and because of her blood loss they didn't spay, I guess there's more blood supply to her mammary area too so they didn't want to try.
But they said she's doing good! And I can pick her up in the AM after 9am...
I won't relax until I see her though.
