Help my sister with her vet bills

I'm trying to raise money to help my sister with the vet bills for her cat. She would never ask for help so I am, for her. This is what happened in my sister's words..

"Sweet Patate had a horrible accident, most likely hit by car. She didn't come home one night, which she's never done before. I left the door open for her and found her the next day, laying in blood with her jaw completely broken, stuck open off to the side. Poor thing could barely breathe. I rushed her to the vet where she had to have jaw surgery and a feeding tube put in. I had her home for a few days and then noticed her back end was causing her serious pain and her breathing was getting shallow again I to rushed her to the Calgary emergency vet where she's been for a couple days. After doing a head CT, they found she has multiple head fractures and is partially blind. She needs another jaw surgery as it is split in half and the first surgery didn't stabilize it enough. The other fractures will take a few weeks to see if they heal on their own. My heart is breaking and l'm at a loss on what to do."

UPDATE: Patate has had 3 jaw surgeries and the last one with the dental specialist has helped so much! Her jaw is straight and closing properly again and she is recovering so well. She’s becoming herself again. Thankfully the pet insurance covered a huge part of the bills, which have already added up to over 30k. But the portion we had to pay is still over $4000. Anything donated is a huge help and truly appreciated!
