The spider command is the best! It actually refers to any bug that I don't want to catch myself. Just the other night I used it to sic them all on a giant mayfly. My old house was infested with spiders, which is how it started. Beckham can jump over 6 feet straight up from a sitting position and Posh has this amazing ability to go from sleeping to grabbing a fly out of the air in .00000001 seconds. If I find a bug, I tell them there's a spider and they all get excited and come kill it. If they find one they can't reach, they will howl and meow until someone lifts them up or knocks it down.
