The nine year old daughter of quantum physics professor Jonathan Carnegie has rejected her father's attempts to comfort her in the wake of the disappearance of her pet cat, Edison. The animal has not been seen for six days after leaving the house last Sunday, and Marie Carnegie is pessimistic about the cat's fate. "I just know he's been run over by a car. I'm so upset, and my dad is just making things so much worse with this dead cat in a box, alive cat in a box, superposition thing," she said today. "Also, I really, really wanted to call him Fluffy," she added.
