1) Noise from Chinese wayangs and Malay weddings
2) Noise from quarrelling human, which is louder and longer than cauterwauling from un-neutered cats
3) Noise from home karaoke sets
4) Leftover of human feeding on.....everywhere lah...and from human food preparation thrown out of kitchen windows
5) Sanitary pads discarded out of the flats
6) Smell from HUMAN urine on staircases,
HUMAN poo on quiet staircases of multistorey car park!
And smell of urine in the lifts!
Human urinating in public in broad daylight!
