The new trail cam has arrived, and I now have a better idea of what has been going on around here. When I caught those youngsters I thought that I just had Mama coon to deal with. Turned out that I had more of a coon problem than I knew about. Count the coons in the video! I have them locked out of the dog food now, so hopefully they will move on to greener pastures. I know of at least 3 of my neighbors who leave cat food out at all times, which is probably what drew the coons in the first place. Let the coons go pester them. I wonder if they realize how many coons they are feeding in addition to every feral cat around.
Now I know why I couldn't catch these coons in my live trap, although I suspected as much. Look at the size of these guys! This video shows one trying to squeeze into the trap. Now the door is messed up and won't close. I put it away for now and will fool around with it later.
