Equine escapologist is an online star
A video of a horse using her mouth to unlock her stable and then free her equine friends has become a viral hit.
Mariska was filmed by her owners opening her own stable door, then walking over to her friends' boxes and freeing them as well.
She appears to unlatch the doors with her teeth and then push them open with her nose.
It appears that the Fresian mare has a talent for escaping as the video also shows her letting herself through gates in the yard.
The video - entitled Mariska AKA Houdini - has become an online sensation with more than 415,000 views in two weeks.
