Cat and the rooster

There was a cat and a rooster wondering by a lake. Both were famished, looking for any food they could find, but to no avail. Later on, the rooster finds himself focusing upon a worm, inching its way nearby. The rooster then proceeds to chase and then pounce on the worm, eating it quickly. Resting after his meal, he rubs his belly in pure satisfaction.

The cat looks at the rooster and thinks to himself,"Well, if he can do it, I can do it." Not long after the rooster eats his worm, the cat spots a mouse scurrying nearby the lake. The cat raises its tail, arches its back, and with all its might, attempts to pounce on the mouse, only to end up in the lake. What is the moral of the story?
