From a few feet away, the metal trays look to be holding tiny rocks, plucked by a very particular and tidy collector. A closer look reveals that each tray holds not rocks, but remains – one holds the bony bits of a ferret, the other a cat. Both were pets, and both are done with their job as companions.
One more thing they have in common: After their deaths, they were brought to this place, where their little bodies were carefully and lovingly handled and reduced to bones. While their earthly hourglass has been turned, in death they are part of something new.
