I have this feral cat that seems to have a broken leg. will not eat or drink and is outside in -20 Celsius. i cannot get near him he hisses and when he tries to run he cries. I just feel just horrible. one vet told me to shoot it if I cant capture it. Another vet said his leg will heal on its own. The other one said. hey its saturday i dont work on weekends. So what am I to do. please help.he is suffering/ Im afraid he wont last the weekend.
