It dosen't usually get hotter than this, but it could be this temp for 4-5 days at a time, so I'm wondering if that'll be okay.
One thing my sister does for her ferrets (Completely different from snakes, I know) is put frozen bottles in their run to keep them cool. I've seen people do this in England alot (we don't really have AC built in) but put the frozen bottle in front of a fan to blow cold air about. I'm not sure it'd work, and also not sure if it would be okay just to put a frozen bottle in the actual tank?? I'm thinking it would also help keep the humidity up, but then again if one of the snakes curls around it that seems like a bad idea... I don't know. It's probably a really stupid idea, thoughts?
