We always regard dogs as man’s best friends. But what about cats?

Cats can also do us a favor sometimes.

Here is a comparison of the two animals.

A Friend Helps You When You’re Sick.

DogsWhen Catherine lay down on the sofa, Pepe stared(盯) into her eyes and kept sniffing(嗅). After being pushed away, he suddenly jumped onto her chest. That’s when Catherine felt a pain that made her visit a doctor, and a fast-growing cancer was found. Months later, however, Pepe started staring and sniffing again. It seemed strange, but sure enough, Catherine’s cancer had spread.
CatsAlana immediately finds a chair when Tee sits and stares directly into her face. That’s because Tee is warning her that she is about to faint(昏倒), which can happen as often as three times a day. But Alana won’t get hurt if she sits down. Not only does Tee warn Alana, but also her husband. Then the cat stays with Alana until she recovers.
