3 month old gray squirrel in need of help. He is barely eating. Does not want formula, water or pediylte. Has been 2 days now since he's had fluids. I've given him a few grapes to try to hydrated him. I noticed an occasional whistle in his nose and a snorting. I'm afraid its pneumonia. I can't seem to find antibiotics that are prescription. He is very tired in comparison to most days. Usually runs around the house, now does not want to leave bed. If anyone knows of a Vet that treats squirrels in the Portland oregon area that would be helpful.
