Unfit Mother in the Making

I totally just dropped my guinea pig (a.k.a. Leo) on his head. I was holding him and he was jittery and I shut the door and it make a loud noise and he started squirming and fell two or three feet. And now he's angry with me. If you were here, you would hear him angrily cooing in the background.

I've assessed the damage, and so far it looks like he just has one pretty badly broken nail. Not too much blood. But he's still seems pretty pissed off. I'm just worried that I broke something inside of him...

This is one of the many reasons I will never have children.
