Cat Clicker Game
Click the cat to increase your score!
Score: 0
In this game, whenever the user clicks on the cat image, their score increments by one. The current score is displayed in the "Score" section. The `catImage` variable represents the `<img>` tag, and the `score` variable represents the score display. The score increment happens inside the click event listener added to the `catImage` element.
