One day Mr. Ness was in the classroom. A cat walked into the room. “Hello， Mr. Ness，” said the cat. Mr. Ness looked at the cat. He was surprised. “Who are you？” asked Mr. Ness.
　　“I am Dan，” said the cat.
　　“You can’t be Dan. Dan is a boy，” said Mr. Ness.
　　“But I am Dan，” said the cat. “I just know how to turn myself into all kinds of animals.”
　　“Well then prove it and turn into a lion，” said Mr. Ness.
　　Poof！ Dan was a lion.
　　“Don’t eat me，” said Mr. Ness when the lion looked at him.
　　“I am not going to eat you，” said Dan the lion with a laugh.
　　Poof！ Dan was a cat again.
　　“What do you do when you are a cat？” asked Mr. Ness.
　　“I do all kinds of things，” said Dan.
　　“I like to go fishing. Fish are fun to catch.”
　　“Sometimes I climb up in trees.”
　　“How do you get down？” asked Mr. Ness.
　　“Most of the time I just jump，” said the cat. “One time a fire fighter came and got me down.”
　　“I also like to play with string when I am a cat，” said Dan.
　　“I sometimes even like to drink milk.”
　　“One time I was a space cat，” he said. “I went out into space. After that I got a lot of mail.”
　　“I read my mail every day，” said the cat. “I even got a letter from President Bush.”
　　“I am glad you like being a cat，” said Mr. Ness.
　　“It is a lot of fun，” said Dan.
　　Poof！ Dan was a boy again. He liked being a cat and liked being a boy.
