Take a look at the passage again:
My cat Fuzz loves to sleep in inconvenient places.
Lately she prefers the computer table. Where
her long hair sticks to the mouse pad, covers the keyboard, and clings to
the screen of the monitor.
You chose the second part, Lately she prefers the computer table. This part has a main clause: She is the subject; prefers is the verb. A fragment will not have a main clause.
