Dogs are considered as man’s best friend. But what about cats? Sometimes cats can make equally wonderful friends. The following is a comparison of the two animals.
A Friend Helps You When You’re Sick

Dogs	When 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.
Cats	When Tee sits and stares directly into her face, Alana immediately finds a chair. 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.

A Friend Saves Your Life

Dogs

Ryan fell into the water by accident. The river was full of melted snow, and Ryan was very cold and his body temperature was dropping dangerously low. Luckily, he was found by Chelsea, who was playing with her dog, Zion. “Zion knew the boy was in trouble,” says Chelsea. “Ryan grabbed onto the dog’s collar, and Zion just turned around and came straight back to the shore.”

Cats

“I was napping in my bedroom, and then I was woken by Joey screaming and running back and forth,” says Bernice. Then she found herself surrounded by smoke. With Joey alongside her, she managed to get out of the door. By then, flames(火焰) were shooting up from the basement.
“I found him in a mailbox when he was young and now I feel very fortune. Without him, I’d have probably died in the smoke.”
