Honestly, if it's that important to breed the animals, why do you have them? Only for breeding? If there is a possible risk, why would you want to take that for your sake and not the animals.
I do not completely disagree, because we still do not know, so I'm not attempting to put down anyone (especially Tim) because I know you all still have healthy wonderful animals. Just playing devils advocate.
I'm not willing to put stress on my snake through a possibly stressful situation, but that is my choice from what I have learned. When digesting food takes more energy from a snake than slithering at the highest speed, and there is no break from this energy, or the food is too small to make up for it, I think it's possibly causing more harm than good.
But, then again, because their so young, and they wouldn't be power fed at adulthood, I wonder how much of an impact it would have on the body of a snake for it to be powerfed for it's entire life v.s. just adolescence.
