How can I be sooo disgusted by human feet yet want to tickle little toe beans so badly.

We have an orange cat that I threaten to tickle his toe hairs all the time (his toes splay out when you get them and he gets all feisty, yet gentle playing, i know he really loves it). If I heard someone talking like that over a person's feet, I'd prob get a lil sick. Even knowing full well what they walk through, I'll take cat tootsies over human ones all day.
