Hi, I have a hit-by-car adult squirrel and my local rehab does not open for another 10 hours. I have him in a carrier with a towel in a quiet, dark place. From what I observed, he seems to have at least a broken leg and possibly a head injury (He ran in circles for a moment when first approached). Is it safe and advisable to give him some metacam tonight? I have a small amount of 1.5 mg/mL EloxiOral. If so, any advice on safely giving it? Thank you.
