It consisted of teams of kittens playing on a small replica football field. There were real sports announcers, celebrity guests, and a referee. The most common infraction was biting the tail of an opponent. All three of my cats watched it, but Opie was the real Kitty Bowl fan.
Advertisements between game play exhorted people to go to an animal shelter and adopt a kitten. Photo of gameplay below followed by adoption advertisement.
If the program is repeated, I recommend watching it.
