Another angle is to consider if "kitcat456" is a typo or a variation. For example, "KitKat" is a known Android version, but adding "456" might be a stretch. Alternatively, "Kit Cat" without the hyphen could be a different reference. Maybe it's a video game mod where users create patches for videos. If that's the case, forums like Reddit, GitHub repositories for the game or mod, or fan sites might have the information.
