Cats and sunlight: Why do they like to lounge so much?

Heat Search
Cats are naturally attracted to heat. Basking in the sun allows them to maintain their body temperature without expending too much energy.

Vitamin D and well-being
The sun helps synthesize vitamin D, important for bone health and calcium regulation. Although cats do not synthesize vitamin D directly through the skin, they absorb small amounts when they lick themselves after exposure to the sun.

Satisfaction and relaxation
Basking in the sun is also a source of comfort and relaxation for cats. Sunlight promotes the production of serotonin, the feel-good hormone, which can contribute to their overall happiness.
