Geez I should have read a lil more into the scenario before making such a closed minded response.
With my younger snakes I sometimes tug on the tail of their prey while their consuming it, sorta mimicking a struggle. And I can't see anything wrong with that really.
Now what I had thought earlier was someone playing tug of war with a Burm in a way that someone would with a fu*king Rott. If that was the case, my previous statement stands.
