I have a year old injured feral male cat.He has a large hole behind his ear in his back cheek. Im not sure if another animal got him, if someone shot at him, or if he was sideswiped by a car. Any advice is welcome, how do i clean it up for him,;;;;MUST i take him to a vet;;;;;; what about rabies shot;;;;,,, where can i get antibiotics for him. Just need to know what you would do in this situation. He is tnrd. But not a tame cat. He will come to me but noone else. Hes one of a colony for free roamers i feed. Vet care is physically tough for me, and financially next to impossible. Help please?
