5 week old squirrel has been eating really well from a 1 ml syringe. Switched to a 5 ml syringe and now he is making clicking sounds when breathing. He did swallow too much at last feeding and had some formula come out of his nose. The clicking sounds isn’t constant, but when it happens, it’s with every breath. I’ve determined that Baytril is best, but how do I go about getting it?
