A cute kitten peeking out of a cardboard box.

The ad opens with a kitten peeking out of a cardboard box, looking at a fish tank. It then transitions to a close-up of a Whiskas Junior cat food pouch. The kitten is then shown eating from a bowl on the floor, before being cuddled by a woman. The scene shifts to a whimsical underwater animation with a cat-themed submarine, featuring the kitten inside, surrounded by animated fish. The ad ends with a close-up of the submarine and the Whiskas logo.
