This evolutionary trait allows them to remain in a state of &#8220;vigilant rest,&#8221; making them highly attuned to the single, long monophasic sleep block of their human counterparts.<\/p>\n<p>Myth Buster: Staring at you while you sleep is not a predatory behavior. It is a Homeostatic Check-in. Your cat is monitoring your vital signs (breathing, temperature, heart rate) to confirm your physiological stability during your period of &#8220;vulnerability.&#8221;<\/p>\n<p>Actionable Step: To mitigate 3:00 AM &#8220;zoomies,&#8221; utilize an Automatic Feeder.
