Stray needs Help.Watch The Video

I am needing to find some help for this poor guy.He's a feril/stray that has been around our neighborhood for the last year or two.We would normally shhoooww him away because he would come over and beat the crap out of our cats.Around two  weeks ago I seen him coming to make his rounds(spraying).When he finally got to the yard I noticed him walking very slow with his back end really unstable and low to the ground.I went to see if I could get a closer look and was heartbroken at what I seen.I offered him some canned food and he accepted without hesitation. We have now been feeding him twice a day and he doesn't even leave our front porch or yard any more.But even with the food in his belly and a shelter we made for him to sleep in, his infection that's in his ear,face and throat don't look to be getting any better. We don't dare try to touch him to see what's going on with it.He IS NOT okay with touching.He defenitly needs some medical attention that I just don't have the money for.And I'm afraid that if I bring him somewhere as a stray , having no one in his corner fighting for him, he will just be put down. So I am really tore with what to do.Let him have life and hopefully he survives his wounds......or take the chance of him getting euthanized....He seems like he can be a good kitty and it sucks to see him suffer and not have anyone in his corner to care for him.Gofundme is the only place I have to turn to for help.Please, if you have even a couple dollars to spare, join me in being the voice for this sweet kitty.He has lived a rough life, you can see it as his face is covered with scars.He deserves life free from this pain and suffering.I don't know how much an emergency vet visit for him is gonna cost.I have no clue to the extent of his injuries other than what I see on the outside which there's a pretty good list.As long as I have something to put down just to get him in there and started with, I will figure out the rest .Thank you for your consideration.  -Stephanie
