OMG Cat reacts to the biggest discovery yet on Mars.... the Mars Rat! Watch the video.
The image was captured by Mars rover Curiosity at the Rocknest site on Mars
with its MastCam camera on sol 52 (Sept. 28, 2012) of the mission. The Mars Rat is actually a rock that looks like a rat or is it a hamster, but don't tell that to the real Mars Rat on Twitter.
