* A man can run faster than a cat. Humans are generally much larger and have longer legs than cats, allowing us to cover more ground quickly.
* A frightened cat can run very fast, but they are still limited by their size and leg structure.
However, the question doesn't say "a man" can run faster than "a cat." It says "a man cat frightened cat." This is a bit of a word puzzle.
