Read the following context and answer the question.
Context: This is always a nice realisation , even after god knows how many years of working there . My toe is bruised from Kathie ( the horse , not the worker ) freaking out and standing on it and it never stopped raining , so it was wet , cold and treacherously slippery . However , Rod still makes me smile and Marlene has grown into a beautiful and sweet mare who will do anything you ask of her . Even the ginormous Coco the stallion ( shut up about the name . We know . )
Question: What may be the reason for the horse standing on their foot ?
Answer:


They got spooked .
