This PR includes a few visual and structural tweaks to the cat element in the game:

Changed the cat's shape — updated the cat's appearance/styling.
Rounded the corners — replaced sharp edges with curved/rounded borders (border-radius) for a softer look.
Added a div wrapper — introduced a dedicated container div to define and control the cat's position within the game area.
Why

These changes improve the cat's visual style and make its positioning within the game more structured and easier to manage/update going forward.
