Help with Copper’s Amputation

Hi, my name is Hannah. We have had a stray cat that we named Copper coming to our house every night. Slowly over the past year he changed from being terrified of us to cuddling with us and our other animals. He has been in and out of our house and considered a part of our family for around 6 months now. On Thursday April 16th at 2am we found him hiding on our deck with a completely limp leg. We think he was hit by a car, left on the street and slowly crawled back to our deck for help. We took him in for x-rays and he has 2 pelvic fractures, tons of fractures in one of his paws and a dislocated leg. In order to live he needs to have his leg amputated. We would really appreciate any donations to get him back to health.
