I notice most cages tend to have some sort of lighting element. Is this merely for light or heat? We put our Cookieboots near the windows and let sunlight come in on her and her cage. Also since its August winter is nearing and I read all about the importance of heating your little hedgie to the just right temperature. I have read about heating blankets for the general bed/nest/snuggle area but the remainder of the cage well...should we get a space heater and keep her in the bathroom where we can maintain the temperature warm or is her being the the apartment with the heater blowing air towards/on the cage enough? Near then I do plan on getting a thermometer to gauge her temperature accurately.
