In KY, the Fish & Wildlife, Humane Society
, and Emergency Clinic were never really helpful when it came to catching animals. The Emergency Clinic was probably the best of all of them, but we were the least equipped to catch anything. (I went by myself one time - ignorance is bliss - and threw a blanket over a Cooper's Hawk to catch him. Injured wing; we treated him at the clinic for a while, I took him home for a while and he finally healed well enough for release.) Usually both of the other places would tell them to call us.
I'm not trying to rain on your parade; I'm glad to see someone else trying to help these little guys. But be prepared to spend part of your day on the phone calling not only those organizations but the vet clinics, too. If you are lucky someone will have a cage that you can borrow to catch him in and you can have a vet lined up to check out his injury before deciding what to do.
Raccoons are my very favorite of all the wildlife I worked with. I'd love to know what happens with him!
