I have a baby squirrel with pneumonia. We've had him about 3 days and I hadn't managed to get him to drink formula just squirrel blocks. Today he started to eat the formula but since he wasn't used to it he immediately aspirated. It's about 5 hours later and now he is clicking and breathing through his mouth. Please help I feel just absolutely horrible and completely at fault. He has fur, eyes open, weighs about 190 grams. I have liquid suspended amoxicillin, 40mg/ml . I called a few emergency vet clinics but because we don't have a license (apparently it's illegal here in PA) they won't even see him. I don't know what to do, and any help is appreciated
