Miez doesn't like walking on the grille

My cat slowly walking on, but then jumping over the grille until she finally walks around it.
Should put a mat over that.
Edit I know there us a need for drainage use a coco mat or dense but still capable of letting water flow thru it.
Why though even bother? This is just a small hop for her plus the grille isn't even as wide as the door. She simply prefers to hop instead.
