Cat litter!

Oxford bins are hardly objects of beauty.

They aren't even particularly functional, given that the 'green' recycling bin is the blue one, the 'brown' dirty landfill one is green, and the other one is brown, I think for throwing in the towel.

Number 83 Lime Walk has the right idea, an amusing bit of suburban subversion, by ever so gently pimping their bin: the middle one is now for cat litter!
