We have lots of street cats here in Turkey and one of the cats I look after in the street got a swollen eye a few days ago. I took him to a vet yesterday since it wasn't getting any better and the vet gave me two different eye drops to use. I used them last night. Today I tried to use them again after I came back from school but he didn't show up. Now he did but he has blood all over his face. I think he scratched it. I called the vet and she said I have to catch it and she would put something to his head so that he can't scratch it anymore. She also said I should take him home for a few days but he doesn't let me to get close to him and runs away as soon as he sees me. What do you think would happen if I can't catch it? Would he be okay?
