There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Cougars also kill horses, both domestic and feral which can also be dangerous prey and probably near the size range of elk. I read of one event where a big grizzly attacked a horse and it ended up with the horse killing the bear. In the same book, I believe it is in 'Man Meets Grizzly' by F.M.Young ( I have several ), it states that some horses know how to fight and some do not. Those that do can often fend off predators. I also remember reading that probably, during the Pleistocene, American horses were likely preyed upon by cougars and hunting them may be instinctive to the big cat.
