Lee asked me if my possum was a Bush Baby and I thought I'd let you know what they are in Australia (as opposed to Africa where they have a real live animal called a Bush Baby that looks surprisingly possum-like!)
To me, Bush Babies in Australia are fictional creatures. They are forever tied to the wonderful creations from May Gibbs who created the Gumnut Babies (I got this picture in my blog from May Gibbs' website [linked above] today) the Big Bad Banksia Men, and so on.
The possum that boards in my bottlebrush tree is actually a Brushtail Possum and there are heaps of cute images of them here.
Lee, I'm glad you asked! I would never have searched for these cute pictures otherwise!
