Sunobu Megacolon Surgery

My little baby Sunobu is in need of Megacolon surgery. She can't have a bowel movement by herself due to the Megacolon issue. So far she has had multiple enemas which besides being expensive on their own are very painful and traumatizing. Even after these enemas she can't have a regular bowel movement, which causes her to be unable to eat and drink normally. We have tried diet changes as well as medication and neither of these things are doing enough and if she doesn't get the surgery most likely she will have to be eutheniszed.

    I got Sunobu as a birthday present when I was 13, and she means the world to me, I love her to the moon and back, she's my best friend. So I am begging anyone if they can help towards my cats surgery it would honestly mean the world to me and her. Thank-you for your time.
