You know how cat's eyes glow in the dark? Why not harness that power to good use? That, at least we presume, is the premise behind this nifty Cat Rechargeable LED Flash Light. ($10) No batteries are needed; about 20 seconds of squeezing will recharge it and give you around 8 minutes of light, making it perfect for nighttime trips to the restroom, camping, or general hijinks. We don't, however, recommend trying this with an actual, live cat.
