This woman complained to the town council - I was told that there were cats in the void deck by the TC. When I called her, it turns out that she was complaining about a cat on the third to fifth floor of a block and it looks like it wants to attack her. I asked her to describe it and she said it looks like it wants to jump on them. It turns out that the cat likes to follow them around. When they try and shoo it, the cat just sits there and looks at them. Once it gave her sister a scratch as she walked by hence the complaint that she had been attacked. This happened months ago and the cat has not 'attacked' since.
She also said there was another 'scary' cat at a nearby block. I asked her how it was scary,and she said it just looked frightening.
I explained that cats rarely attack for no reason. I said the cat might be trying to play with them and hence may have scratched her sister by accident.
