Brand New BP owner... condensation in the hide?

[AdamF]

I was thinking that could be it too.. but the substrate is dry? I'm just really paranoid that he is going to get an infection of some kind.

Pythons and snakes in general do not urinate wet like mammals. Their kidneys pass only dry urates, this is definitely not a case of evaporating urine condensing under the hide.

Besides, the amount of urine you would need for condensation to build inside the hide would smell awful WAY before it started condensing.
