I noticed in the photo that the place is fenced-in. Is it electrified? Is it to keep out Polar bears, Snow tigers, Snow Leopards, etc?
Mostly to keep out the "hunters". In Italy they have a weird law that states that hunters can come into your property whenever they want unless it is fenced off, and I have domestic animals that I don't want them shooting. However, up in those trees there are also huge wild boar (they come down to the road at night), and also the rather large Crested Porcupine has to be kept separated from domestic animals. Several months ago I spent a couple of hours taking the spines out of the throat and chest of one of the neighbors' dogs (a Labrador). en.wikipedia.org/wiki/File:Brush_tailed_porcupine_Berlin_Zoo.jpg
