To use these Mad World Cat posters and prints, simply pick a spot in your room you'd like to decorate, and hang them up on the wall using your own frame or mounting method. Make sure to choose a dry and clean area to avoid any damage. When it comes to maintenance, gently dust the surface with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they can damage the print. If there are any small stains, you can lightly dab the area with a slightly damp cloth. Just remember, these prints come without frames, so you'll need to get your own according to your style and the size of the print.
