Well, no not necessarily, its good to know that too, just in case. If your snake can get to the glass, there is a chance that he can burn. That's where the repti carpet would come in, or newspaper, what ever you choose. Something a little thick to insulate the heat.
It's a good idea to measure the surface temps, since that is what the snake will actually be touching. Early on, we bought a temp gun to just shoot and get a reading from. I had my probes actually in my snakes hot spot hide. So I could just glance and see what temps he's feeling. We look for 90-95 for a hot spot. Using the carpet or newspaper to insulate it, this can easily be met.
Just try a few things out, you may find something works really well.![]()
