i was feeding one of my adult balls a live rat and once it striked and coiled up around it i closed up his tank and put the cover back on top which must've make too much noise (vibration) and he stopped constricting and the poor rat was suffering because the snake didnt kill him all the way he later then finished up but i just wanted to give a heads up to people that didnt know that that would happen if you accidently disturb them in the process.
