With our furnace malfunctioning most of the winter (just got a new one 2 week ago), it was a fight just to keep all my snakes healthy. And it worked out well, not one incidence of illness among the bunch.
But the only snakes that I could take the chance to cycle were the colubrids.
Is it too late to try and cycle the spotteds into breeding? I'd really like to see some hatchlings this year

I didn't want to risk turning down the heat and having the furnace die and leave them with an unacceptable level of heat to deal with the ambient drop.
