He has. He's defecated both white/yellow stuff and recently brown smelly feces. Which confused me, because I thought brown feces came after eating a meal.
I like your plan. I'll dim the light minimally and wrap and stuff his cage. I'll also transfer the heating pad from my corn snakes cage. Her cage is usually fine in temperature anyway and shes a pig when it comes to food.
Will a heating pad be enough though? Those things usually aren't that strong..
What about a blacklight?
