My mother told us this funny story. My grandfather was a zookeeper so mother was a child she lived in a zoo with her parents. One day her friends came to visit her. Mother wanted to show her pet cat. Her friends waited to see a cat. Is she grey or brown? They said You will see in a moment, laughed mother but they all screamed loudly when Stripy came running in and put his paws on mother's knees. Stripy was a tiger cub.
