This topic makes me LOL! Raja has been known to clear a room with his butt
It's usually a combo of wet food & those freeze dried liver treats... silent but oh so deadly!! They "hang" in the air too... haha sry, that's pretty graphic.
Just the other day he had his first and only (that I know of) audible one. He jumped up wide-eyed and stared at his butt like "what was THAT??"
