3 adjectives to describe wildcat

Little wildcat.

One morning, in May, McKinley, the teacher, was sitting alone at his desk, busily engaged in writing, when, hearing a slight noise at the door, he turned and beheld an enormous wildcat, with her fore feet upon the step, her tail curled over her back, her bristles erect, and her eyes glaring rapidly about the room, as if in search of a mouse.

He was thus enabled to catch sight of the startled wildcat bounding for the shelter of the trees, having deserted its meal in sudden fright.
