Dear cat friends and lovers , here is an illustration of machiens that nature built as opposed to ones it didn't yet build , if we deduct any machine we see michanics at play . So maybe we'll see experimental biology that would try to make new natural machienes with new features . see for example that cells can possibly make fire , so if this unorganized phenomina we can design an organism that can light a fire https://www.quora.com/Is-it-biologically-possible-for-cells-to-produce-fire

Meanwhile the street cats are having a good time with catnip :)
