Also, it's easy to think of things in human terms instead of animal terms and to underestimate/overestimate the sizes of things. I remember when I got my dog as a puppy. I set her up in a child's playpen with some lino underneath so that any wee at night wouldn't go on the floor. In the morning I'd fetch her out. One morning, she just walked straight through the bars.... She could fit through all along LOL She was such a good girl, she stayed in there anyway. I'd judged them as narrow enough to confine her - not so.
A lot of scavenging animals are amazingly flexible and they will be very persistent when it comes to getting something to eat.
