Introduction

If you live with a cat, you’ve probably seen this scene many times. A bright patch of sunlight appears on the floor, sofa, or bed, and within minutes your cat is sitting or stretching right in the middle of it. Even if they were sleeping elsewhere, they somehow notice that warm spot and move straight to it.
This habit can look adorable, but it also makes people curious. Why do cats love sunlight so much? Is it just about warmth, or is there something deeper behind this behavior? The answer is a mix of comfort, instinct, and simple pleasure. Cats don’t choose sunny spots by accident. Understanding why cats sit in sunlight spots helps you better understand their natural needs and why these quiet moments matter so much to them.
