Alright, thanks! Now it all makes sense, why I was told to get a temp gun and a thermostatReally glad I asked, although I guess I would have ended up buying the right things (by some stroke of luck!!).
Another question - are 2 hides necessary for a carpet python? I just went out and bought two, but when I put everything in the tub there is no way I could fit 2 hides and a water bowl in there. Of course I'll be upgrading to a larger tub/terrarium once the snake is larger but for now, would one hide do? If so, does it go on the warm side or the cool side?
