On Saturday morning we woke up to start the day, Kaiser (three years old) went to sit on the potty, I went to the kitchen to make coffee. I heard the cat meowing at the door so I let him in. Kaiser went to his bedroom for a toy when he saw the cat. Then he said, "Hey, Guy's in." (the cat is named Guy) Then he walked to the front door, saw it was closed then looked at the cat and asked, "How did you do that?" meaning how did the cat open the front door to let himself in.
