Does anyone know this black and white cat on Chesterfield Gardens?

This little cat has taken to spending it’s evenings sitting on my windowsill, staring mournfully through my window. It’s not thin or scruffy so I’m presuming it has an owner, but I’m just checking because it’s very persistent, and it looks super sad when my cats get their evening Dreamies! I’m on the Green Lanes end of Chesterfield Gardens and it’s hanging out in my front garden.
