Yeah, she's seen 3 different vets in the last couple of months.  They did a
geriatric bloodwork and everything was in normal ranges for even a young cat
(Bandit is 16 now), her BUN and creatinin levels were fine.  They tested her
urine and blood pressure and both were fine.  They looked into her eyes very
carefully and the retinas were fully attached, there wasn't even a trace of
cataracts, and all the blood vessels looked healthy.  The last vet surmised
that there might be a tumor pressing on her optic nerves at the bottom part
of the front of her brain.  Since there is nothing I could do in that case
anyway, I didn't take her to have an MRI for confirmation of this since she
gets *SO* upset at the vets (I would too if I'd been burned on 40% of my
body and had to have my skin removed from the results of a tooth cleaning!).
I wouldn't want to put her through anesthesia just to tell me something I
couldn't do anything about.

She's not in any pain at all, still eats lustily in obvious enjoyment, purrs
up a storm during our skritching session, and manages to find her way around
without any problems (and beats the snot out of any cat who happens to get
in her way).  So, I'm just taking all the good days I get and trying not to
think about the future at this point.  I'm just hoping the end comes easily
(don't we all wish our babies would go in their sleep at a *very* advanced
age??!).
