Humans and their "detatchable fur"

Okay. something has been bothering me for a while, and only since my human Lanna had her head fur cut have I really noticed how weird this is. Humans don't have their own fur.

Strange.

Now I have fur, Trance has fur but the humans in my apartment do not have fur. Is that normal?

Don't get me wrong, the humans have some detatchable fur. Fur-derivitive I call it. They call them coats, shirts, pants. Sometimes though, the Lanna Human will go outside in the detatchable fur called "skirt" and leave her legs without any fur on them! Imagine that!

The Edmund Human does have fur on his chest, but it is sparse. He sometimes has fur on his face too, but then he'll go into the bathroom and come out with it gone.

Both Humans do have fur atop their heads tho. More than I have on my head. Can't they grow it so it will cover their bodies like my fur covers my body? Huh?
