Hey. I just read this and found it fascinating. THe link is provided below. Scientists are wondering if there is some environmental factor, potentially an endocrine disruptor of some sort, that is causing even wild animals - such as horses grazing on pasture- to keep getting fatter and fatter. Here's the link where I read it.
Maybe there were too many raccoons in the study. Coons and bears (basically big coons) have seasonal hyperphasia, meaning they never ever get full. They just keep eating and eating, plus they have super slow metabolisms. We have a 31 lb raccoon that eats nothing buts nuts, fruits, vegetables and raw meat. And he is free to come and go....and he is soooooo fat!
