I was given a five week old grey squirrel baby. He was only one who survived. He was found under a tree, two siblings dead. He had a little blood on his nose , and his inner thigh is open and was teaming with small maggots. I cannot find Capstar tonight, I looked in three animal stores. He is very weak. I am hydrating him, and flushing wound and taking off maggots. I am afraid they are internal as when I set him down, there are drops of blood. I have seen them in his rectum. I have raised several squirrels, but never with this nasty problem HELP!!What could have caused this injury? Crows, hawk, fall from his tree? Can any other meds kill the nasties??
