I asked my daughter Gabby to get into the Fox snake enclosure. They had dumped their water and it needed cleaned and refilled. Seconds after taking the screen off Gabby yelled for me. The male Fox snake is an aggressive feeder and he thought it was dinner time. He gave her a good solid bite and wasn't wanting to let go. Once I got my finger inside the lower jaw I was able to pry him off. Gabby got cleaned up and returned to the snake room. She said she wasn't mad and that he was just hungry. She's a great snake helper.
