Yes, it's for belly heat. My question was more so that with my room temperature range (68-72) do you guys think that it is nescessary to have both a UTH and a RHP or should I be good with just a RHP. Also that if that same type ZooMed UTH would work on the AP cage (wasn't sure if it would be bad for the plastic or something) but it sounds like based on your answer, a UTH on AP should be fine. Leaving just the - do you guys think it's necessary in my scenario to have both?
