Viacom’s new “studio model” strategy will see Nickelodeon Animation produce a new Big City Pets series for Netflix, as the company begins to turn its brands toward developing shows for OTTs and other third parties. Sky Rat was originally greenlit by Nickelodeon in 2013. Big City Pets was created by Craig Bartlett (Hey Arnold!, Dinosaur Train, Ready Jet Go!), and Dave Polsky (The Buzz on Maggie).
