Hey Snakeman how's it going? Living as well in Southern Cali the weather we have been having lately can definately cause fasting especially for the older ones but it has alot to do with the ambient room temps. I have one room that never gets under 78 at night 84 day and they are all eating fine.My breeding adults are in another room that gets down to 74-75 nights and 79-80 days and most of them are not eating much. So I think it comes down to the night temps in the room they are in. Try checking temps with a digital thermometer. I have 400 watt oil filled heaters in each room on Herpstat pros to control rooms otherwise they could get into the 60s, real cold for a BP! Cool snakes will go off feed.
