Word Ladder Run, Cat, Run

This is a new idea I am trying. You start at the bottom of a ladder with a given word and using the clues they give you, change the letter you are told to into a new word. For instance, starting with cat, change the word in the next higher part of the latter to "The puppy ____ on my lap", the answer being Sat (change the first letter obviously. Doing this with the clues, she got cat, sat, mat, bat. Now this may seem easy to Megan, but I started her with the simpler ones so that she can get the idea of it.
