This is the adorable moment a girl shrieks with joy at receiving a surprise hamster for her birthday - only for her new pet to bite back. Grandmother Mary Jane Peterson had bought the furry critter as a surprise gift for her granddaughters 6th birthday. And as little Mackenzie walks into the room and spots her new pet, she bursts into shrieks of joy, shouting: ‘A Hamster, a hamster!’ But as she reaches in to hold her new pet - it bites back. The shocked six-year-old recoils in shock and declares to the camera: ‘It bit me!’.
