I have a ten year old male gray tree squirrel. He has been drinking a lot of water and has had dark colored urine. Now he is clicking and crying and is at the bottom of his cage. I desperately need help right now on how to treat him. I have amoxicillin 500 milligrams. He seems to be going down wound is in pain. Please help me. My phone number is (XXX) XXX-XXXX. Thank you , Taunie
