Usually I get tagged during feeding, I have some very aggressive feeders that will latch on anything warm when you open their tub on feeding day.
Basically they wait at the front of the tub and get the hand that opens the tub (my temperature is higher than most people so I have always been a bite magnet because of this), the last one lost two teeth because of it so now I open the tub with a hook, not because I fear for myself but because losing teeth can lead to serious issue.
