I just saw a squirrel by the front of my house that is dragging his hind legs. I didn't get close, don't need him freaking out and he was squeaking bad enough. He's shaking some too. I can't afford to have a "rehabilitator" come get him and do what they do and I don't want to see the poor guy suffering either. What can be done? I've called one gal and am awaiting a response, but I don't know how long that will take and I don't want the guy getting getting beat up by other animals, dogs, or the weather. Anything I can do otherwise? Please advise.
