Our two cats spend 50% of the time they're awake doing that! hahahahahaha! They love pulling off their ninja attacks on the dogs so they are always hiding... waiting... ready to attack... I copied a trick off Jackass 3 and tore up an old measuring tape so I can roll up the tape in my hand and hold it that way with a paper clip. When I throw it where ever a cat is hiding and it pops loose my cats jump so high they show up on local weather radar.
