i grew up in the woods, so i know better then to try and approach anything that might not want me to, but there's no one particular species, other then humans.
Mice and rats. I have a totally unreasonable fear of those. I have no knowledge of having had an issue with them that could have provoked the fear but I am irrational dealing with them. Outside is not such an issue but if I know there is a mouse in the house, I am almost in panic mode.
I was afraid of dogs being a child, to help me to overcome it my parents had bought me a puppy and it really helped!
Yes they make me jump too. Even though I know small field mice are quite cute I think it's their quickness is what gets to me, they kind of shock me when they do run by. :d
Mice in the house is different for me too. I think they are cute.. but not when they are unwanted in my house. Still hate spiders.. but getting better with them. Cockroaches are just disgusting. earwigs terrify me.
