Why did the kitten come as soon as she heard the WeChat ringtone?

Cats recognize their companions by smell and communicate through movements and body language, so the meaning of meowing to cats is not for communication.

Cats are interested in the voices of other cats in mobile phones, mainly because they are puzzled, because in their view, they should be similar, not unknown.

Cats are interested in barking, mainly the sound made by male cats when they are in estrus and courtship. It is relatively cold that cats make sounds similar to human speech, but they don't know this sound.

Cats are very clever animals, good at imitation and know how to please their owners, so their response to their owners is to imitate their voices.

Similarly, their interest in the sound of cats in mobile phones is also based on the owner's viewing mentality. At first, they were very willing to cooperate, but more often. Knowing this principle, the cat ignored it.
