I started to handle mice for my job and noticed that they tend to defecate and/or urinate when they are scared. The fear is induced by me, because I need a long time (due to inexperience) to grab the mice and then move them from one cage to a new one. My question is why?
I tried to look up literature for this behavior and there are different fear behaviors for different animals some shake in fear, some play dead but I could not find something for fear induced defecation. Therefore my question: What is the reason behind the "Fear induced defecation"?
I am especially interested into the neuroscience pathway behind it.
