The British Hedgehog Preservation Society has won a years-long fight with McDonalds to shrink the size of the opening in a McFlurry (a frozen edible-oil dairy slurry) reduced. The present wide-mouth McFlurry cups serve as fatal hedgehog traps by sucking in 'hogs who lick up the left-over slurry, get stuck, and die.

Up to now the opening in the container has been large enough for hedgehogs to get their heads into for a lick of the left-over dessert — a trap they have then been unable to withdraw from, so dying of starvation in untold numbers.

But from September 1, the wide-mouthed opening in the lid of the McFlurry containers will be reduced in size, making them too small for the sugar-loving animals to get their heads into.
