A Shower Thought is the type of curious thought that only enters your head in the contemplative peace and steam of the shower cubicle.
Tonight's thought comes courtesy of Stephen in Dunedin, who asks: ""Why are there so many rabbits in the South Island, particularly in Otago, but are not anywhere as much of a problem in the North Island? Grass is grass isn't it?"
Emile Donovan puts the question to Otago Regional Council community coordinator for biosecurity Sophie Gibson-Pinn.
