We have an outdoor kitten (barn kitten) and she is afraid of everything. We started the tractor to go get a bucket full of wood and she ran. I tried to pick her up to pet her and she got skittish and hid.
Aw, poor kitten. I've had some cats that never got over their fear but eventually got used to me. It can be a really slow process but they are so adorable that it's worth it.
Poor kittie! Well lets hope she gets over her fear of loud things but not loud cars. It might be a good thing because if she is afraid she might stay out of the road.
