Perhaps start a go fund me page to help with bill for treatment. Call some local vets and inquire about your unfortunate circumstance and they may be able to give you other options to ensure cat gets the care she needs.
There are rescue groups that may help financially. I would join the Facebook group "South Carolina Pets" ( black and white heart with paws). It's normally for posting pets for adoption/sale but there are many rescue groups on there as well. Post your story, and where you're located. Someone may help.
This is a forum to ask questions to the public. If you insist on using this vet, call them. They might have payment plans, but most vets don't. This vet may be able to help. Or call Pawmetto Lifeline.
