Hahaha, I thought only Cash did that! He doesn't do it at a particular time, but whenever he has too much energy - about once a day. But he looks soooo funny coz his legs are flying everywhere, his ears are pinned to his head and his butt is tucked under

. Honestly, he looks like a demented rabbit when he does this

.
Ps. Sometimes I hide somewhere in the house, call him and when he gets near, I scare him like Boooo! He goes crazy!! After that we just watch and laugh
