This is very interesting. a153fish, I would certainly take any of your advice as accurate and reliable. Light must have alot to do with it. I do know for certain that my Bairds rat snake relates to photo period and photo period alone. Like clockwork he stops eating when the days get shorter. My corns dont seem to care. I will try my hand next season without wintering and see how it goes. liljenni, The girl i WANT to breed is a terrible eater and i am not planning on breeding her. The girl i am going to breed is like a garbage disposal. My dumerils is doing wonderful btw thank you for asking. A perfect snake minus the constant 'peeing' lol.
