Ok I'm sorry. Maybe the others that have posted didn't notice, but your numbers are just way off. You need to cool the entire cage down. If you have an AMBIENT temperature of 90 degrees, then I'm sorry my friend, but you need to lower that. And a "cool side" of 85 is just too high. .. you aren't providing your snake with a proper temperature gradient.
90 degree hotspot. 80 degree coolside. If you keep those numbers, the overall ambient will be perfect... your snake may be climbing to find a cooler temperature. Your cage is hot bro
