In my country i used to take care of stay cats and dogs in my area feed them buil for them shelters me and my friends sometimes if we see an animal injured we took him to the vet to let check on the animal then taking care of him and his injured eye in my home .Some of the cats gets in fights when they injure themself i use to take care of there injuries till they get better. Honestly i did not work in a pet store or official shelter but i used to care of a lot of animals in my area give them shelter because of our country economic crisis we used to take care of them check on them if there injuries need vet depends on the severity of the injury.I read a lot of animals health and behavior to make sure if they are well .
