My brother saved a approximately 5week old baby squirrel, the mother and remainder of the nest was destroyed by a cat. The baby has been eating great until last night...now it is "clicking" when it breathes. I have it beside a vaporizer and on an insulated heat pad but I don't know what else to do :'( I have clavamox and amoxicillia but I don't know the proper dosage. Please help this little baby means the world to me
