Im not saying i know better. That's why i started this conversation. In the pet store they are also kept at room temperature and the guy there told me they adapt. I did not believe him at first, but i don't know what to think any more.
As i said Pufi is very happy and his poop is ok. He eats ok and plays alot.
I did not intentionally kept him at high temp. Just few times when i was not keeping a eye on the temp, the AC was running but was not able to lower temp, and as soon as i have seen that i switched the AC to max power.
