Give a hamster a running wheel and you already made him happy!
As in the case of any statistical data gathered during a longer period, there are peaks and bottoms of the performance, so why should it be otherwise with Maszat? Some nights she runs more than 15 kilometers, some nights she makes only a few steps.
But are you interested in what was the biggest achievement made by the speedy hamster during a single night? How many rounds did she made in the wheel? How many kilometers do they mean if recalculated?
