（1）＿＿＿＿＿

Cats don’t use words, but they make a lot of sounds to tell what they’re thinking about. So do dogs. They use different sounds to “say” what’s on their minds, and “chat” with other dogs or their owners.

（2）＿＿＿＿＿

Cats are great climbers. They love to stay in trees and even on the top of houses. They can jump long and almost always land on their feet. Still, when it comes to traveling far, dogs are hard to beat. Some of them can run or work all day.

（3）＿＿＿＿＿

Dogs’ noses know better. They smell the air and get a lot more information than cats, for they have twice as many scent cells（细胞）as cats. But cats’ hearing is king. They can hear many sounds that dogs would never notice.

（4）＿＿＿＿＿

Most dogs like to hang out with other dogs. Most cats prefer to be alone. In order to get along, cats usually have to be raised together. Cats might like to be held in their owners’ arms, but they leave the pet parties to the dogs.

（5）＿＿＿＿＿

Dogs can be trained to follow different orders and do all kinds of tasks. They can help search for lost people. They can serve as guide dogs for blind people. Some can even help police officers to catch criminals. Cats can be trained to jump through hoops, catch toys and give high fives.

When a cat curls up on your lap, or a dog rubs your head or licks your face, you’ll know who the perfect pet is. Whichever one you own!
