The initial close-up of the cat's wide, startled eyes.

The video features a close-up of a cat with wide, startled eyes. Text overlays appear sequentially, describing symptoms or behaviors associated with high cortisol and stress. The cat's expression shifts slightly, and it moves into a more relaxed, lying-down position as the text progresses. The background is a textured rug and a white barred structure, possibly a gate or crib.
