You want a slug-related traumatizing story ? I had a cat with very long hairs, there was a cat door to the garden outside but usually he slept inside. One morning i wake up and feel the cat close to me in the bed, something very common. I start to pet him on the dark being half awake only. After some time i feel something wet in his belly fur, but as I’m half sleepy I don’t react and keep petting him. Only after what was probably a long time, I realized that something is wrong, turn on the light and see a slug curled/trapped inside his fur, I was touching it with my hand for several minutes!
