Horses

Just east of the Rockies, between Banff and Calgary, large fields are occupied by horses and cattle with only a barbed wire fence as protection. Wolves, bears and cougars do live in that area and sometimes prey on domesticated animals because of that. Better protection would solve that and would also improve the reputation of the predators very much. Not only are domesticated animals in a poorly fenced area easily accessible (and who can blame a predator for taking that chance when it is offered), but it also gives rise to something that has contributed very much to that bad reputation. When a predator enters such a fenced area, the animals kept there will panic. Even though the fence has not kept the predator out, it does keep the potential prey in. Under natural circumstances these would flee and leave the predator with the prey it initially caught. However, on such a field all the panic and chaos gives the predator an overkill of stimuli which may cause it to chase down all that chaos and kill everything it can catch. That is why you will sometimes hear that large predators are mindless killers and that they kill more than they need just for the fun of it. But in fact the real cause for such behaviour is that when humans entered and claimed as their own an area where large predators have lived for hundreds of thousands of years before tem, they failed to adapt to that completely!
