A Rat On Mars?

The Mars rover Curiosity may not have killed any cats, but it appears to have found something that resembles a rat.  It's really "a piece of dusty orange rock", but it does kinda, sorta resemble a small rodent.

Read the story at HNGN.  If you're on Twitter, you can follow the Mars Rat.

Interestingly enough, this is not the first time that a martian rock reminded people of an earthly creature.
