Well, must say I hadn't seen this thread before and was quite and "interesting" read.
I decided to do quite a bit of on-line searching for "gerbils being toxic to snakes" (which I found very odd indeed), and found nothing but items on 'feeding gerbils to snakes'. And, in fact, a few saying that gerbils are the natural food of ball pythons in the wild. NOW, being that this info comes off the net, I am not saying this is 100% correct, but if indeed it is the "choice" food of the wild balls, then I would hardly think them to be toxic to snakes. Personally I feed gerbil pinks to my stubborn eaters and they are growing just fine so I guess so far, so good.
I will say that I have fed raw bits of chicken to extreme stubborn feeders with great success. In fact, I raised one up in '03 for quite a few months that way till I could finally convince it to eat mice. The growth rate was no where what it was for pinky fed babies, but the snake lived and is still alive today and doing well. I, personally, wouldn't hesitate to do so again if it means saving the snakes life till it will get on the "preferred" food, but as I said, the growth rate was not that of the pinky fed ones so I could not see myself feeding an only diet of such foods.
I have no intentions on getting into any "flame" wars so will refrain from any major comments on the Hot replies, but I will say that I agree Vinman, that if you want to be taken seriously, you need to present facts and not get heated when opposition is given to your ideas. This is the best and only way to work through new ideas to see if they "hold water" and if there are many leaks found. If many leaks are found, then we have to assume that the 'new trial' failed. It is great to experiment and find if there are other good ways of doing things, but there has to be proof that the new method actually works or is beneficial. So, if you want to pursue your "study" of this feeding method, keep records of what you are doing and present facts to people and if opposition is presented, put out facts holding to your side or check to see if the opposition is right.....and refrain from name calling. Simple.
Good luck with your trials on what you are doing and I truly hope that whatever you do is beneficial for your animals.
