One of mine tagged me this past Sunday on feeding day. As is usually the case, if you get bit, YOU probably did something wrong and in my case I am guessing that I didnt have the FT Rat quite warm enough. My body was warmer. I had the rat on the end of 8" hemostats and she struck right past the rat and tagged my thumb on the hemostat handle. She turned loose instantly. Her bottom jaw teeth connected on the print side of my thumb and did not bring blood. The top teeth got skin where it is thinner just behind the thumbnail and it Barely broke the skin enough to make 1 big drop of blood. This was from a 400ish gram female Pied. Like I say though....I did something wrong to cause this. When I re-heated the rat to a higher temperature, her aim was perfect and she got what she was really after.
