Answer:
oh and here I love my cat because it he is the best cat in the world. He is all black and his name is Mr. Kitty. I got him on my 6th Birthday, when he was just a kitten. There are many funny stories that I could tell you about him, but I think this one is the funniest.
My Kitchen leads out to the back porch, where Mr. Kitty's food is. Right beside the door, which has a large window, is the dryer. One day we were eating dinner and Mr. Kitty was sitting on the dryer looking out at the porch. Suddenly, he takes a running leap off the dryer, right into the door window. Smack!! He hits it dead on and flies back. Dazed, he sits up and looks
around for a few seconds. Then he gets up on the dryer, looks at the door and off he goes.
