Im not saying my room smells just inside the cage. Only half the top is covered so it is deffinitly not a ventilation problem. I only had the snake 3 weeks and spot clean every time. All poop smells i just think the wood absorbs it more and the heat mskes it worse. Its faint but still there. Never had the problem when i had colubrids because i housed them on paper towel in a rack. I will just clean more often and remove the bedding in the spot where he defecates.
