Key word: Unattended- But you didn't leave them unattended.
But anyway my guys have been eating f/t from when they were babys, and they still have a EXTREMELY strong feeding response how do i do this you ask? Well after the snake strikes and is constricting the dead rodent i tug on its tail and feet to simulate resistance, and use the BACK of the foot, not the part with nails to kick gently at the snake. Actually i was trying to prove this point to my brother last week- fed one live, one f/t... Presented room, got the SAME response. To the op- go back to ft, try this and i guarantee with doing this and making the rat 'dance' by grabbing it by the surf of the neck and making it move, you will still have aggressive feeders, with the safety of f/t. It is safer for the snakes and i think what you did (if if ever did that to a living creature i would keep it to myself not boast about it) was unnecessary and cruel. Trust me if its attended , then your snakes will not get hurt and there are other methods that cause a lot less pain to the rodent that can be used. There are lots of people on youtube that cause the rodent extra suffering, and its a living thing needed to be treated with respect, and we dont need more. I understand that you were worried and it was your first time, but Please, for the rodents sake dont let it happen again.
Well that was the longest post i ever mad on this forum... hope it was worth it.
