Vet Fees for My sick cat

My pet cat Libby has fallen out of a tree and broken her hip and the ball jont in her leg is no longer connected. In order for her to fully recover she has to have an operation. She is currently not eating as she is in so much pain and has already lost weight and her strengh in doing so. We desperately want her to get better but the vet bill is extortionate and we cannot afford up to £1000 straight away. Her sister Tibby, whom she has been with since birth is already mourning her absence as she is being kept at the vet under heavy sedation for her pain until we can come up with the money for her operation.

Your help would really be appreciated. Thankyou for your time
