The Distant Monotonous Yapping Thing!

So...a mystery is solved...(Pic from Pocket Pets)...The distant monotonous yapping thing is a Sugar Glider.'The sugar glider (Petaurus breviceps) is a small, omnivorous, arboreal, and nocturnal gliding possum belonging to the marsupial infraclass. The common name refers to its preference for sugary foods like sap and nectar and its ability to glide through the air, much like a flying squirrel.' (Wikipedia)'The Sugar Glider (Petaurus breviceps) is a species of small gliding possum found throughout the forests of eastern Australia. It’s most common call is a bit like the ‘yapping’ of a small dog and can be very monotonous!' (Wildambiance.com.)
