Cats have accompanied the man around 4000 years. In ancient times cats have been worshiped and have been considered animals with hidden powers as if they were gods; in Egypt it was called miu, which meant seeing.
Cats can inexplicably produce a sound called "purring" with a frequency from 2 to 150 hertz that can heal wounds like enema and reduce stress to people, even helps people with heart problems, so it is a good method of healing and relaxation, the unexplained purr.
Cats despite not showing their emotions meow to communicate with humans and not with other cats; they have trouble seeing under the nose; cats greet each other by brushing their noses; they can produce 100 different sounds and dogs only 10, and they sleep 16 hours a day.
