Why do cats always sleep on quilts?

Cats are relatively afraid of cold, especially those who are small, short-haired, young and old and sick. So I like sleeping on a warm quilt. In addition to keeping warm, of course, it is because the quilt is soft and comfortable. There is also herd mentality. If one cat thinks the quilt is so comfortable, other cats will follow suit and sleep on it. In fact, cats are more afraid of catching a cold, especially smaller cats (lower basal metabolism than large cats, so less calories) and cats with short fur (long hair is better than short hair to keep warm). A bigger, smaller and older cat (a little nursing cat, an old cat needs to keep warm because of its physical condition), and a sick cat no longer needs to be afraid of the cold. For this reason, cats like to sleep on warm quilts. That's why cats don't go straight to bed. Of course, besides keeping warm, cats sleep because the quilt is soft. Compared with the hard floor and cat nest, the owner's quilt is definitely the softest place, because the quilt. There may be many cats left. Animals are most likely to get hurt when they sleep. When the cat is resting, it will definitely choose the safest place to sleep, and the quilt will have its own taste. Sleeping on a quilt full of smell will definitely make cats feel safe.
