Campbell's Hamster: What is on the Other Side of the Door?

Because the same white furball that was eating popcorn upside down on that piano keyboard seems desperate to get through ::~~

Upside Down Campbells Hamster Eats Popcorn on Piano Keys

I've never seen anything like this:

Campbells Hamster Wheel Fight

These dwarf hamsters are called Campbells. I used to have one, only he kept threatening to bite me whenever I tried to pick him up (hated being grabbed round the sides). Very beautiful furry coats though. Unfortunately my room was too hot really in summer for him and his housemate who was a Winter White (and much kinder in temperament). Their fur was the highest quality fur I have ever felt on a domestic pet. Better than any fur coat I've touched. Good thing the fur trade never discovered these creatures. (Also it would take about 1000 of them to make a floor-length coat. Ooer.)
