I did a search but realized it was going to take so long and i feel
like i urgently need someone's advice or help about this, so i'm just
writing it all now.  I am sorry about that.

Before i go into what is happening, here is some background info:

My cat, Madeleine, is fourteen years old and has always been very
healthy.  She started to have some kind of strange allergy problem
about a year ago, so once in a while, she'll go into the vet for a
cortisone shot.

She got sick recently, with a cold, where she was sneezing and
coughing, with a runny nose.  The vet gave us antibiotics and she
seemed to get better.

I also have to emphasize that, even when she had the cold, she was
still very lively.  She's always running around and she likes to catch
those fuzzy cloth hair bands.  Even though she's considered and "old"
cat, she has remained healthy and happy.

We took her in again and the vet said that her teeth not only needed
cleaning but that some really needed to be removed as they could
threaten her health.

So, the other day, she had the cleaning and teeth removed.  They used
the gas anesthesia, i wouldn't go to a vet that used the injectible
stuff, after a bad experience i had some years ago.

Anyway, she hasn't been the same since.  I expected her to be out of
it for a little while, what with the surgery and pain relievers and
everything.  But wouldn't eat.

Then, one day, she gobbled up a little dish of cat food and i was very
happy and she seemed better.  Bu the next day, she wouldn't eat again,
and she was falling over.  She seems to be very weak.

Yesterday, we took her in again and the vet used an IV to give her
fluids and nutrients all day, and he also force fed her.  Last night,
she ate some food that the vet gave us on her own but she was still
very weak.  I thought it would be a good idea to walk her down the
hall, just so she could maybe start to get her strength back.  I took
her to the end of it and she walked back on her own but stumbled a
bit.

But today, she won't eat again.  And she can barely walk or stand up.  
I've helped walk her down the hall a couple of times today, and she is
managing to use some strength, but something is wrong.  It is as if
she's lost her coordination.  I just force fed her a little while ago
and now i have her with me in my bed, where she always sleeps.

She is purring but i know that purring doesn't always mean a cat is
content, it could mean she is in pain.  She looks like she's quivering
a bit.  I've got her wrapped in blankets.  She seems so spacey and
different.

After the surgery, which was supposed to make her healthier, she's
worse than ever.  I am really scared.  Another thing that is worrying
me is that she doesn't seem to have defacated or urinated since the
surgery.

Like i said before, even when she was sick she was very vivacious and
lively.  Very energetic.

What could have happened?  Has anyone else experienced this?  Does
anyone know what could be happening and what i can do?

I love her so much and i can't stand to see her going through this.  
I'm determined to nurse her back to health, and am doing what the vet
said, but it doesn't seem to be enough.

I'm just scared and hope someone can offer some advice.

Thanks.
