Cats dream, and relevant research shows that cats dream about catching prey. Cats' sleep is the same as that of humans, which is divided into deep sleep and light sleep, which occur alternately. The content of cats' dreams is related to their behavior during the day. "Think about it every day and dream about it at night", the same applies to animals. When a cat suddenly wakes up from a dream, meows, or even runs over to rub against you, it is most likely having a nightmare.

Performances of cats sleeping and dreaming:

1. When a cat is sleeping soundly, it will occasionally chirp, lick its mouth with its tongue, and sometimes even drool. This means that the cat is sleeping. If you are eating delicious food in your dream, be sure not to wake it up, so as not to disturb its sweet dream.

2. A sleeping cat’s legs will suddenly move, as if it is having a spasm. Moreover, the eyelids and eyeballs will also jump, the lips will move, and finally the back will be arched. Then it could be a dream.

3. When the owner finds that the cat wakes up from a nightmare, he can give some petting or snacks appropriately, which can effectively relieve the cat's mood.
