I found a baby squirrel, looks about 4 weeks. I made a formula from Henryís pets recipe and am trying to feed him but doesnít seem to be consuming food. He doesnít seem to be dehydrated. Heís gasping/clicking some. Iím afraid he has aspiration pneumonia. My vet doesnít treat squirrels. Thereís no wildlife rescue near me. How do I get an antibiotic for him? Iím keeping him warm. I donít want him to die!
