A chocolate birthday cake with lit candles sits in front of colorful stacked presents. Four tiny kittens pop out of the pink box in the middle, meowing the tune of a song. One kitten takes the lead to sing a soulful happy birthday song. The camera focuses on the kitten's face. The video ends when the pink box tips over onto the chocolate cake, splattering it across the screen. A small orange kitten pops out from under the pile of crushed cake with a candle atop his head. He meows and the words "have a purrfect birthday" appear on the screen.
