Cats and dogs are the most close animals to human beings.

Cats and dogs are the most close animals to human beings.Cats and dogs are just like guards, baby siters, friends and so on.Though they are very familiar with people, they still have many differences.As my observation, the differences are as follows.The first one, dogs eat more than cats.Seconds, dogs can observe your happiness or anger than cats.Third, cats can take care of themselves, let themselves become clean. But dogs need you to clean them.Forth, dogs will yell to strangers but cats cannot.Moreover, you can train the dogs to pupu or peepee wherever you want, but the cats can only do it on their cats' sant.Besides, cats' paw grows very fast, dogs are not.In my conclusion, cats and dogs are totally different. Not only in the appreances but also in the behaviors
