“Direction and duration of gaze figures prominently. For the cat as hunter or prey, surveillance and vigilance are locked together. Releasing gaze from another cat, signals affiliation in blinking and alternating the direction of gaze allows for an antagonist to move away. Barriers to sight lines, are security sought in the cats’ seeking dens and resting spaces with raised sides. Relying on the safety of sight lines, when vulnerable, can be seen in preferred elimination with uncovered litter boxes and why removing box coverings can be effective with unacceptable elimination in the home."
