Help with Moose Surgery

Hate that I even have to ask for help. Something that I really dont do but I need help now. You all know our cat had kittens. My daughter got to choose one to keep. She named her Moose. Moose has Pectus Excavatum. How the vet explained it to my daughter is that God hugged the kitten to tight in mommy tummy. Surgery is needed sooner then later to correct her chest and help her breathe and give Moose a chance to live. Unfortunately pet insurance won't cover the surgery. Greatful for any help.
