Thank you all!! :YMHUG:
After waiting all day, I had to call (grr) and ask for an update on Sushi. It doesn't look like the test results came in today, so I guess we'll be waiting till tomorrow. I did find out that the IV has fluids & diuretics. Hes on 40% oxygen; there's a chance they might try weaning him off the oxygen tonight.
That's all I know for now.
Yes, Julie the vet & I have been discussing whether the fluid will return. The test results should shine a lot of light on that. : )
