I am one of the people who does not cool the snakes and I never had an issue with it. I do light cycles starting in October through the end of March and start my pairings in October. Once I notice a male will not lock with a certain female she is done breeding and will not have a male with her again. I put the male in for 3 days with the female and then out for 4 days. That is about it honestly. All my temps stay the same and feeding stays the same. Each is always offered and if not taken then they are offered fresh the next week. I found this is what works best for me. Here is a link to Ralph Davis Reptiles who does the same thing and has it more detailed http://ralphdavisreptiles.com/matrix...l_breeding.asp also on that site has an area for the terminology and also punnet squares and all that fun stuff.
