Oh I HATE rat bites! I've only been bitten a few times but the worst was long ago..
Sometime around 1996 I had gotten a huge rat for my albino burm. Back then feeding live was all most people knew. I learned my lesson fast! This angry giant rat started twisting the moment I tailed it. I didn't even have the cage door open yet so my idiot self quickly put it on the floor to prevent breaking its tail off. In one motion I put it down, put my other hand over it with my hand behind its head, and it twisted its neck and chomped down!
The top incisors just grazed down the side of my finger but the bottom pair of teeth went straight in the underside of that finger. Straight to the bone! I still have a little scar there that is quite visible.
Needless to say, I was not feeling badly about feeding that rat off.
