Not a cage, but wires supporting a loose rockface
A little help with grooming !
Japanese snow monkeys
The Japanese snow monkey, or macaque, is a species native to Japan. They get their name as they live at northern latitudes where snow covers the ground for months of the year. No other primate lives in a colder climate (except man of course !). These were photographed near Yudanaka some 100 miles north of Tokyo.
