If you are wondering what raccoons are capable of . . one chewed through the side of a live catch trap and escaped
My friend in Michigan had one chew through the wall in her barn where the wall met the roof and then chewed through the inner wall to get to her chickens. This was after it broke through the chicken wire on her chicken house windows (replacing with hardware cloth stopped it) and killed all her bantam buff Brahmas, which were the parents of my birds. These are extreme cases though.
Hope you catch that sucker!!
