Cat hiding behavior is a primary stress indicator requiring appropriate refuge provision and stress source identification rather than attempts to force social interaction.
Cat hiding welfare has been transformed by the cat-friendly practice movement, which has moved veterinary environments from seeing hiding as a problem to recognizing it as a welfare need. Cats denied hiding opportunities in clinical and shelter settings show higher cortisol, reduced immune function, and higher infectious disease rates. The practical welfare intervention is straightforward: provide adequate hiding options in any environment where cats experience stress. The common owner response of pulling cats out of hiding to reassure them is counterproductive — allowing retreat is the welfare-correct response.
