Have you ever received a singing birthday card? You know, the ones you don't know have any sort of sound until you open them and they start playing a song or a sound effect? In this video, the singing birthday card is playing the 'happy birthday song' sung with cat meows. And, the cat in the house, well, needless to say, is not very impressed with the birthday card. Check it out. I thought it was so funny. The funniest part is when the cat attacks the card the second time. Enjoy.
