I just went through 5 different raccoon attacks to the tune of losing 18 of our girls over a 3 week period. He broke the window out of the aluminum door, tore fencing off, broke a latch and more. I kept tightening and new latches, you name it I tightened it. I put electric fence around the bottom and he climbed on the roof from an overhanging tree. Finally took trapping him to end the morning bloody misery.
