My hamster-expert uncle told me that hamsters have fast metabolism—they’re very active creatures. It’s either my sister’s hamsters just have a problem, or they’re just freaks of nature. I prefer to attribute it to the latter, for the simple reason that it’s really hard to find the underlying cause. I’m a bit new to hamster care, so I really wouldn’t know as much as I would about dogs.

The underlying cause is probably just weirdness. :P

And here’s Wendy posing for the camera.

Wendy the Weird

Well, at least Wendy’s trying to make an effort to exercise. Peter is so lazy that he doesn’t even bother—the exercise wheel is just a makeshift hammock for him.
