I had a 2100 gram female do that to herself. She was a he, now, he is a she, but, we named her when she was a he. Her name is Oscar after Oscar the grouch. You cannot take her out of the rack without a hook, you have to be very cautious when you have her out, and, you cant touch her when shes in her home. She sleeps belly up and is a bit retarded. Anyways, she thinks everything is food and so thus she tried to eat me and instead of getting my hand she got herself. She preceded to strangle herself and she coiled around tighter everytime we tried to free her. We left her alone for about 15 mins and she had given up on trying to kill herself at that time. Luckily, no blood was spilled and no broken bones seemed to have come from it. Snakes are strange at times...
