I haven't had a kitten in a long, long time, but my Butter is the exception to the RCA theory. He's an adult and still takes great pleasure in hiding around the corner and leaping out on our ankles, bare or not. And just to prove he's not so smart , he will crouch in the broad daylight, convinced I can't see him (when I surely do see him) and leap on me then too! And he doesn't do it just once, but over and over again, getting a few steps ahead, crouching down and leaping again! LOL!!! What a silly fellow he is!!

Welcome to Pet Talk! I think you have started off with a "bang"!
