S02E05 Kitty Kontest

Kaz signs Ami and Yumi's cats up for a competition, only to discover that the cat contest won’t take place until October. Undeterred, he decides to register the cats for a dog contest, disguising them as dogs. However, things go awry when the cats are prompted to bark and instead let out meows, leading to a chaotic scene where they, along with Kaz, are swiftly chased away by the agitated dogs.
