Random House is releasing details of its partnership with PBS to develop The Cat in the Hat Knows a Lot About That!, which premieres in fall of 2010. The project is just entering development, according to the Animation Insider website. PBS announced at Showcase last month that comedian Martin Short has signed on. The show will center on Sally and Nick, 6-year-old neighbors, and their adventures with the Cat in the Hat — and, yes, Thing One and Thing Two.
