A friend has a ten year old, 6 foot long bull snake. At this time of the year a peculiar occurrence has been observed. Right after this snake , ( he thinks it is a female ) sheds, it starts biting its own tail continuously and even thrashes around. Feeding it doesn't stop the behavior. It lasts about 10 days and doesn't happen again until the following June/July shed.
WHAT IS GOING ON ? He is afraid it will break the glass or injure itself.
