Kitty Litter!

When the city's cutest kittens start being abducted by gigantic teleporting cat men, The Aquabats trace it back to Kitty Litter, a ferocious feline using unwilling kittens to power a gigantic cat robot as part of a scheme to cover the planet with garbage. When most of the band is kidnapped by Kitty Litter, it's up to Crash to get over his pet dander allergies and save the world from becoming a global trash heap.
