If you want cute, try a Sugar Glider. Petaurus breviceps is a small 'gliding' possum. This is the kind of pet which is only awake during the first hour of so after you get home from work. They sleep the rest of the day.

If you want funny try ferrets. They get into exceptionally small places and hide [or get stuck] all the time. Actually just weasels with a nicer name. Oh, maybe I am thinking of ferret owners?
