What is the advantage of raising a cat?

On 19th, March morning, my wife and I went to Taichung to adopt a black stray cat that it is my new family member, named O Ti. He has come to my house for one month and then he has given us some advantages.
Firstly, Catching mice is the nature of cats and it is my original motive. My house is apartment so many buildings are very close. Sometime, the mice coming from the building outside through the holes had a party in my living room. I have tried to use the mouse cage to catch them but they always don’t be cheated. My wife and decided to have a cat so I have never seen the mice in my living room. Next, I surprised that the cat also can killed the cockroaches. On day, my son told me that he saw a cockroach in the living room and the cat ran fast and extend his front feet to press the cockroach. Rapidly, the cockroach was dead. I don’t think I will see the cockroaches in my house soon. The last on is that he is family lubricants. There are more laughs,games and happiness in my house. My sons play with him every day. Sometime, he runs in order to let my sons to catch him. Sometime, he removes tenderly around my son body. Sometime, he goes to bed with my son in mid night. My family is pleasure he came.
To sum up, catching mice, killing cockroaches, and family lubricants are advantages of raising a cat. If you would like to a pet, I think the cat is good choice.
