Thumping Gerbil

[trinaye]

I like how the other one comes out and looks around like, "What? What's going on?"

[WhatTheShittles]

lol mine do that too..but why? isn't it like a mating call?

That's their way of warning others of danger. I remember the ones I had, I'd accidentally scare the crap out of one, he'd take off, then the thumping sounds begin.
