Tron's digital world was first envisioned way back in the era of mullets and New Wave, over three decades ago. People then didn't anticipate that the Internet of the future would be filled with porn and image macros of little kitties. This continues to the sequel; thankfully someone decided that the absence of LOLcats in Tron had to stop.
This intrepid kitten sports a jacket with all that electroluminescent piping that the movies are known for. Just make sure not to chase it around; who knows if its tail generates a fatal light wall when it's running?
