Sissy Vet Bill

I found out today my 14 year old baby kitty Sissy has cancer and needs to be put down tomorrow. I can’t cover the cost of her bill until two weeks from now when I get paid and her pain meds will wear off within two days. They won’t put her down unless I can come up with the money and I don’t want her to suffer. She has an appointment for tomorrow to be put down but they canceled it because I don’t have the money. If anyone can help I’d appreciate it. I’ve had her since I was 7 years old and I can’t stand the thought of her in pain any longer even if it’s the hardest thing I’ve ever had to do.
