Jeanette Winterson, famed for her novel Oranges Are Not The Only Fruit, shocked some of her 32,800 Twitter followers by saying: "The skin which includes the head makes a great glove puppet".
Winterson posted a photo of the cleaned rabbit, saying: "Rabbit ate my parsley. I am eating the rabbit."
But her posts drew criticism from some, apparently sickened at her "cruelty".
Jacqueline Looker tweeted: "i unfollow u,u make me sick." The auther countered her critics saying she had trapped the rabbit in a cage next to her parsley bed and killed it humanely.
