Mine are so active. They run circles around their house all day long. Tossing hay and bedding everywhere.
Ninja usually falls over after she eats a lot. I mean just flat falls over and starts snoozing. She is sooooooo cute.
You are very lucky. I am just getting to know mine. I have only had them for a couple of months. Peanut is still not very friendly, but I keep trying. She just runs as if I was carrying a meat cleaver or something. She will come around.
