Small Kitty Needs Surgery

My rescue kitty was born with what they call megacolon.  Her colon is too large and she has trouble having bowel movements.  In the three weeks I have had her, she has seen three emergency vets and two regular vets.

She needs a surgery called a colectomy (they remove most of her colon to give her a more normal life).  If she does not have it, she will have to be put to sleep.

I do not want to believe this kitten was brought into my life only to have me destroy her.

Please help.
