The neighbour's cat sits on the ledge outside unit 06-17 and watches the lift landing as if she owns the corridor. She is tabby, compact, unimpressed. I do not know her official name; I call her Supervisor because that is the job she performs.
Supervisor arrives after breakfast and leaves before dinner, which suggests someone inside feeds her on schedule. She does not beg. She observes. When the lift doors open she tracks whoever exits with the focus of a customs officer who has seen everything and expects little.
I met her properly on a morning when I dropped a bag of marketing flyers I was supposed to recycle. The papers fanned across the tiles. Supervisor did not flinch. A child from downstairs laughed and helped me gather them. Supervisor judged us both, then washed a paw.
Cats on ledges are common in HDB life but this one has posture. She sits centred on the concrete, tail wrapped, eyes half-closed in the mode of someone who has delegated all urgency to humans. When it rains she disappears. When the corridor gets noisy — delivery trolleys, renovation drills — she stays, which feels like a vote of confidence in the building's overall competence.
I write about Supervisor because she is part of the lift landing ecosystem. The uncle at the coffee shop remembers my order; the cat remembers my face. Neither asks for anything beyond presence. That is a good neighbourhood contract.
If you live in a block with a ledge cat, you already understand. If you do not, imagine a small manager who works for fish and silence.
