"Because those that live DOWN BELOW, do not NEED such things as cats to protect themselves," he explained and arched down to the boy, lifting his gloved hand and gesturing across the boy's body as he explained, making 'gutting' motions.
"They like to pin you down and then they gut you, here and here, making your death slooooow and painful, sometimes, they eat you before you're even dead~" He smirked deathly at the child. If that didn't scare him away, he didn't know what would. "Plus, I do not know you, therefore, you must be lying."
