Cats and Sunshine: The Secret Behind Their Favorite Spot in the House – The Scientific Explanation

Cats have a particular preference for basking in the sun, and this is no coincidence. The need for warmth is fundamental, as cats have a higher body temperature than humans and prefer warm environments to conserve energy. This preference has an evolutionary basis, as their ancestors lived in warm climates. Furthermore, sunlight helps relax muscles, reduces stress, and regulates the circadian rhythm, while exposure to a window provides a sense of security and control over the environment. Cats sleep for many hours a day, and bright, warm spots are ideal for this intermittent sleep. However, it is important to ensure the safety of cats, with secure window screens and protection from overheating.
