Start with the room itself
- Where are the drafts, vents, and temperature swings?
- What happens at dawn, evening, and cleaning time?
- Is the cage in a high-traffic or stressful spot?
- Are noise and lighting steady enough for rest?
Only add tools for a clear reason
- Measure first if you think temperature or humidity is a problem
- Use timers when the sleep routine is inconsistent
- Use purifiers carefully if air quality is the real issue
- Keep changes simple enough to monitor
If you cannot tell whether a device is helping, it may just be adding complexity.
