In November 2018, the human behind the YouTube channel The Secret Life of My Hamster built a very clever maze with five different levels to conquer. In the first round, the big blonde hamster ran the course from start (top) to finish (bottom). Next up was a smaller gray hamster, who ran it backwards from finish (bottom) to start (top). They both finished the maze with respectable times and were rewarded with yummy treats for their cooperation and participation.
In this video the hamsters go through the maze. Who will make it better?
About a month later, the same human built “KING-OF-THE-HILL”, a half-vertical maze that tested the upper body strength of each hamster more than once.
