I said MOB in one of my first posts....

Isn't a pig sty a man-made home ?

Anyway, the answer could be a "scrape" - where the animal scapes a small hollow in the soil (usually under a tree) and then lies in it to keep cool. They apparently also find shelter in caves or rock clefts.

or if you want "man-made", they call them "macropod enclosures"

Aww... I think poor Nippy will be as confused now. haha
