Thank you all for your purrs and thoughts.

Because she still hasn't eliminated and threw up this AM again, they
suspect perhaps a partial blockage and will just go in and do surgery to
get the biopsy and look around since the ultrasound detail wasn't
fantastic.  So, she's going for surgery sometime today.

My brother says that the *day* that they committed to adopting Sylvester
was the day that Melba went downhill.  He wonders if her cat antenna
were strong enough to detect this.

I'll let you know how's she doing when she comes out, probably late this
afternoon.
