Why do cats like sunlight so much?

I know that lots of cats enjoy sunbathing, and the science indicates that the sun helps keep them healthy, but I'm not sure I know what you're asking.

I have just noticed that my cat really likes to sit in the sun, and I wanted to know the science behind it

Great question! Your cat can experience what’s called a calming effect, which helps with stress and relaxation. Cats have a good number of melanin in their skin, which can make them dark, but the sun helps to break up that melanin and turn it into a chemical called eumelanin. This chemical helps to improve your cat's physical and mental health, and gives him a pleasant feeling of relaxation and warmth.

Does it have to do with their body temperature as well?

That’s an interesting question.  Studies on both cats and dogs have found that the sun can slightly raise the body temperature of the animal.  On a similar note, the sun can also help to raise a cat’s pulse, which may be one reason why your cat might seek out some sunlight to cool down in warm temperatures.

So my cats like to sit in the sun to help raise their body temparature?
