I have a baby squirrel that is about 5 weeks old, eyes still are not open. When I put him down to roam around, he scoots around backwards and goes in circles. He does step forward also, but tips over and then will right himself again. He will climb up my arm and shirt. Is he so wobbly and going backwards because his eyes are still closed and this be a balance issue? He eats his FV very well. He urinates and poops on his own. He seems healthy except for his movement.
