The correct answer is: Having pets was forbidden under Taliban ruling.
"My Forbidden Face" is a true story written by Latifa, a 16 year old girl, who recounts the events that took place in the five years she and her family lived under Talibal ruling in Afghanistan.
The Taliban had very strict rules: no music, no television, no photographs, no guns, no portraits, no Western books, no education for girls, and no pets.
When they took over Afghanistan, Latifa's family had to hid all of their herilooms, and she had to give her dog to relatives in the countryside and set her canary loose.
