This was my logic behind wanting to feed them smaller meals even though it's less like their feeding habits in nature:

It seems to me one big heavy meal would be more stressful on their system, what with all the digestion, dealing with toxins from the meat etc... its just like overwork, extremes. Whereas smaller meals several times a week might be less "stressful." But then again, I could be wrong, that might be more stressful for their digestive system...
