Sunshine Leg Amputation

Sunshine is a 4 week old kitten who got her leg crushed in a couch near my home. I found her, brought her in, and took her to the vet hospital today. She is going to need her back leg amputated on the right side, and we need help to afford the surgery. She needs this, her leg in infected and needs to come off before it kills her. Any donations help, any at all!
