The video doesn't play when I click it, just opens as an image, so I didn't see if the raccoon opened the door. Raccoons are very smart and strong. If they can get a finger hold under the door, they will open it. If there is not a bar across the bottom of the door to block them from getting leverage, you will need to modify it. Just make sure that however you modify it, the door can still close all the way and doesn't get hung up. Remember, weather can make wood expand and contract, so you must leave room for that.
