Cats are very afraid of the cold, especially in winter. Cats like the sun the most, as being in the sun can make them feel warm. Moreover, when a cat is basking in the sun, it can help it produce melatonin, thereby improving the cat's sleep quality. Therefore, sleeping in the sun can make it feel more comfortable.

Benefits of cats basking in the sun:

1. Sunbathing is an effective disinfectant and can prevent cats from being infected with parasites.
2. Cats should be exposed to more solar energy to enhance their body resistance and make them less likely to get sick.
3. Spending more time in the sun can help promote the absorption of vitamin D and calcium, and can help cats supplement calcium.
4. It can also effectively relieve the cat’s low mood and keep it in a happy mood.
