Anyone who (owns/is owned by) cats knows how completely fascinating they are. They are not like dogs, but special in their own wonderfully bizarre feline way. They have endless quirks and personalities that go on for miles, and always know how to entertain themselves.
These are creatures that have not evolved since the Saber Tooth tigers first slunk out of the jungle. They have not evolved because they have not needed to. They are perfectly designed hunting and killing machines, as obvious from this video. (I especially enjoy the sound effects because I know that that is the sound going through Junebug and Bee's little noggins when they pounce on mice, bunnies, balls of tin foil, my bare feet, or each other.
BOOM! BOOM! BOOM! GOING! TO! KILL! YAH! YAH! YAH! DEATH! DEATH! DIE!
