Help the cat recover from an accident

Ah Meow (what we call her) is a community cat that was apparently abandoned by her owner. Besides hanging out at the ground floor, she would always come up to level 5, where we stay, to meow for food and keep us company. She would come up every night without fail.

One of the nights, she did not appear. She only appeared in the evening the next day, lying on the chair motionlessly. We realized that she had a fractured leg and bleeding nose. Immediately we called SPCA to pick her up.
