Here's the Schedule for when "CatDog" will be airing Weekdays on Nickelodeon (All Times Eastern, and are three hours later on Nick Too)

Morning "Power Hour" at 6:00 AM (Airing with proper Original End Credits)
Midday "Summer Pick-Nick" at 12:00 Noon and/or 12:30 PM (Note: Nick must air the "CatDog" episode whenever the series is nominated, no exceptions!)
Weeknight half-hour at 6:30 PM (Unfortunately, this ep will probably have a lousy [I] "split promo/tailored end credit" sequence afterwards.)
