Jansen said the Orvillecopter is ‘half cat, half machine’, and part of a visual art project to pay tribute to his cat Orville.

Jansen, part of the art cooperative Generaal Pardon, said: ‘After a period of mourning he received his propellers posthumously.’

He added that Orville will soon be ‘flying with the birds’ stating: ‘Oh how he loved birds. He will receive more powerful engines and larger props for his birthday. So this hopping will soon change into steady flight.’
