I am Pixel, a curious hamster. Today, my human put a new wheel in my cage—it shows numbers that glow on a small screen when I run. At first, I didn’t understand why my tired paws weren’t the only proof of my exercise anymore.

As I ran faster, I saw the numbers change, and my human smiled. I learned this digital wheel helps them watch my health closely, which I think is pretty smart for a tiny hamster like me.
