Noises in the roof early morning make people nervous. Rats are the first thought, but here at Wallaby Gully the roof cavity is too small for rats. For the past 20 years a family of Feather-tailed Gliders have lived with us. 

They leave after sundown to scour the forest for nectar, flowers and insects. They come home just before dawn and land on the roof to scurry back to their hiding place. We must be up to a few generations by now after all these years.

They are tiny - the photo shows fully grown animals. This pic is courtesy of Australian Geographic.  

After 20 years I have not been able to get a photo but one did land on my pillow one night!
