Claire & the Cat

Claire & the Cat was a promotional Flash animation for Heroes produced by artist Tim Sale. The images apparently feature a much younger Claire Bennet as she prevents a black cat from being hit by a truck, and is herself hit.
About
The animation originally appeared on Tim Sale's website on June 7th, 2006. Due to the design of the site, the posting was not cached.
Then, the animation was released on the NBC web site for a brief time period in August 2006, then was removed before the start of the series. The events depicted in the animation are not considered canon to the series, as Claire only learns of her powers a couple of months before the start date in the series.
The "link" image to the animation was the fiery portrait Claire in a cheerleader's uniform that (to date) has only appeared in Heroes promotional material.
