Perhaps you should try the local ASPCA for your injured animal.

The local ASPCA would not be able to do anything for him - ours only has a part
time vet. I found this out when a cat that I adopted from there had FIP. We
had asked specifically if he had a URI and were told "no." We had to
euthenize him 4 days later.

"The day may come when the rest of the animal creation may acquire those rights
which never could have been withholden from them but by the hand of tyranny.
The question is not can they REASON, nor can they TALK, but can they SUFFER?"
-- Jeremy Bentham
