i have a gravid boa who is about 85 days from her p.o.s. Her cage temps are 81 on cool side and 91 on the hot side.She is in a 4 foot animal plastics.Her body temp is 89.Is this a good sign of a good clutch?i read 84-88 is normal.She has been as high as 90.Im just a little worried she is too hot which could mean a bad clutch.plus i never see her off the heat unless she is drinking.any thoughts??
