The two-month-old filly had its front right hoof jammed in the metal coffee cup which was stuck on the young horse overnight. Owner, Jenny Tillyer, was able to locate the animal and finally wrestle the mug off the next day and warned members of the public visiting the New Forest National Park in Hampshire to avoid dropping litter. Campaigners in the New Forest have long urged visitors not to litter, as it is a persistent problem in the area when tourists visit over summer. The New Forest, which is famous for its ponies, was last year voted the best national park in Europe following a poll by Trip Advisor.

She is now keeping an eye on the foal, which may have sustained shoulder damage. Ms Tillyer said she set off to rescue the foal, named Blackwell Night Night, in the Stoney Cross area of the New Forest following a call. With help from Mike Maton – an Agister in the New Forest who specialises in the local landscape – they led the foal and its mother Blackwell Moonchild to a local pound. Ms Tillyer, from nearby Fawley, Hants, said: “Mike was able to hold her still, she sort of jumped and put her front feet up. “From there, I grabbed it and was able to wiggle it off. “It’s amazing it didn’t come off on its own but I think she was pushing it on as she was walking. It wasn’t on too tight but it took a bit of wiggling. “There’s no wound or anything like that but I’m not sure if she’s bruised.

I suspect she jumped around when it first went on which could have tweaked the shoulder. “The mug must have been the perfect size for her foot. It’s one of those travel mugs that is nice and firm metal, luckily there’s no jagged edges. “I don’t understand the mentality of people ruining the place by chucking litter around. Agister Mr Maton, 45, from Longdown in the New Forest, also warned tourists. He said: “The foal was very fortunate it didn’t break its leg. It only takes one twist or turn and its leg could have broken. “People need to be aware everyone is entitled to come down to the Forest but remember to take away everything you brought with you.”
