Found a young male squirrel. Extremely skinny and appears to only "lick" at food. Does not "chew" that I can tell. Semi-friendly, and hangs around same area. Appears to be urinating on his own (peed on my outdoor carpet) but does not chew seeds I put out for other squirrels. Other squirrels that chase each other off do not seem to approach this little guy. Gut feeling is he is an outcast. No idea how old he is, but I think young. No apparent wounds, can climb, run, jump, etc., drinks water from birdbath (clean water), and only appears to be able to eat natural peanut butter on a spoon. Acts like he is having trouble swallowing. Cannot see if there are any long teeth but appears to have teeth in front. I put a piece of frozen strawberry out and he appeared to "suck" all of the fluids until he was able to swallow the tiny piece. What can I do to help him?
