The Edible Dormouse or Fat Dormouse (Glis glis) is a small dormouse.
It was farmed and eaten by the ancient Romans (usually as a snack), hence the word edible in its name.
The edible dormouse lives in continental Europe. It was accidentally introduced to the town of Tring in England through an escape from Lionel Walter Rothschild's private collection in 1902. As a result, the British edible dormouse population, now 10,000 strong, is concentrated in a 200-square-mile (520 km2) triangle between Beaconsfield, Aylesbury and Luton. Though this animal is regarded as a pest by some, in the United Kingdom the Wildlife and Countryside Act 1981 prohibits certain methods of killing and taking it, and removing them may require a licence.
