Gee, with all the pets I’ve had, I never had baby hamsters. Unknowable mentioned them and sparked my interest.
Here are three babies learning how to enjoy their hamster wheel. So much nicer than twanging the bars of the hamster cage all through the middle of the night. That’s what my hamster did. Much better to use an aquarium with plastic sides.
(It could be worse. I had a quartet of tree frogs that, um, “sang” all night, loudly. My housemates didn’t appreciate it. The frogs were returned to the wild.)
