I have to agree with everyone else, I HIGHLY doubt Shadow was trying to be mean. And I have an agressive feeder too, it's great in the long run because they RARELY miss a meal so thank your lucky snake stars Does your BF handle Shadow at all? New smells and large objects moving that close to him may have startled him. I wouldn't worry too much especially since it was on feeding day
My Boyfriend handles Him all the Time. He is a loving cuddly snake, Pretty much all the time.. well most of the time anyways
