Is it time to radically re-think pet ownership? In this highly challenging and thought provoking Four Thought the writer Esther Woolfson argues that a lifetime spent sharing her home with a variety of birds and animals - rook, magpie, crow, starling, canaries, parrots, rats and rabbits - has led her to understand just how little we really know about the capacities and feelings of other beings. Pushing us to consider why we own pets in the first place Esther's talk promises to have you looking at Rover, Ginger, Fluffy or Socks in a whole new light.
