Please Help with Kings Surgery

Hello, I am Nani. My cat king has bladder stones in his body, as well as low white blood count. While there are treatments that can help, he is in urgent need to remove a few massive stones that have formed inside of him. Even after surgery he will need a lifestyle change, as well as needing prescription food and medicine to hopefully never get them again. Right now, he needs all the help he can get. Due to recent increases in my mortgage on top of this recent incident with King its become very challenging for me financially to pay for his medical bills. Any amount you can spare will be greatly appreciated.
