Hang Tian's mother, also known as Big Cat Aobai. She was a black-and-white cat and described as the queen of the streets. One month after giving birth to Hang Tian, she was severely injured in a premeditated ambush by a pack of cats due to cold weather and improper recovery. She managed to live just long enough to entrust her one-month-old son to Hang Sheng before dying. A memorial photo of her hangs on the wall.
