I always end up accidentally stepping on kitty tails . When they are lying down I always try to step over them to aviod stepping on them, yet it seems that they always end up moving right under my foot. Maybe if I try to step on them, then I will totally miss them when they move away? But for some reason I don't think that will work, so I just have to keep hoping that they stay still when I am trying to step over them instead of rolling underneath my foot.
