A porcupine called Twinkle is on the loose after escaping from a farm visitors' centre in Cumbria.
The animals can be dangerous because of their quills
The three-feet long, three-year-old female, burrowed under a fence and escaped from Eden Ostrich World in Langwathby, near Penrith, on Saturday.
Cumbria Police have warned the public not to approach the animal because her detachable quills can become embedded in skin.
They are being urged to call police if they spot the animal.
Jim Peet is the founder of the farm visitors' centre which also boasts rare breeds of cattle, donkeys, outdoor pigs, goats, red deer, meerkats, zebras, racoon dogs, ducks and geese.
He said: "Twinkle is pretty cool and about the size of a sheep dog, but porcupines are classed as dangerous wild animals because of their quills."
