or zoo.

My impression was that it was too large for an antechinus. I looked at
google's images, and where it is shown alongside the human hand an
antechinus seems to be about the size of a mouse. The creature I saw
was more rat sized, and I think its tail was covered in short grey hair,
not concentric circles of rubber like the tail of rattus rattus.
