I keep it @ 78 because the front of the cage will get too warm otherwise due to belly heat. I really don't know how we can say Flexwatt is not a fire hazard. You are going to have to use a heater whether you use belly heat or not. I would much rather just worry about the heater than Flexwatt too. As for subadult females going off feed, this has been discussed quite a bit and is not uncommon for them to fast. I can assure you my husbandry is sound and this is actually the exception not the rule. They always go back on feed and do fine after that. Also, if this was an unknown occurrence then Tracy would not have brought it up as a benefit ( l never mentioned the problem). We don't have to agree on this. I'm sure you know what you are doing and what is best for you're situation.
