Ana had her surgery.  The vet removed 3 inches of intestine, she said (I'm
hoping I remember this all correctly) that basically about 2" of her
intestine was almost non-functioning, so that had to go, and then she took
half an inch on either side.  She also did find some old feces in the colon
that she said should pass soon.
She is recouperating at the animal hospital, and should be able to come home
Monday, provided she has started eating and everything is going ok.

Thank you for all your positive thoughts and well wishes.  We really do
appreciate it!
