Help Molly walk again

My cat, Molly was shot by a slug gun on Friday night. The bone has been shattered and she is in a lot of pain. The vet has said the only options are to put her down or to amputate the leg which will cost $1000. I really can't afford that but I also can't bear to put Molly down.

She was a shelter cat but has such a lovely nature and she is family now. It is a tough time of year to try and find extra money but I have to give Molly another shot at life. The vet said she will learn to get around on three legs ok and she is still a young cat - only three years old.
