There was really nothing but good news: Her condition hasn't gotten any worse. The specialist doctor guy said it was nearly impossible for it to go away, so "not gotten worse" is the best we can hope for. For now, she won't need to go onto any life-long drugs. And also good, since this was a follow up ultrasound, the bill was only in the hundreds, not thousands.
Miss Kitty is now busy ignoring me in protest of having been taken to the mean, awful, evil vet. :)
Edit: Her name isn't really Miss Kitty, I just tend to call her that while writing about her.
