Ceramic is heavy. Plastic is cold. Rock is thermal engineering.
Leopard geckos thermoregulate through belly contact with warm surfaces. Not air. Not light. Every hide on the market ignores this. We didn’t.

Crushed volcanic basalt bonded in bio-based EcoPoxy resin. High thermal mass stores heat and releases it slowly through substrate contact — replicating the Afghan highland terrain these animals evolved in.
