I've noticed Chibi is not using her humid hide as much. She is eating fine and is looking rather plump (and is gaining weight), but she is using the hide a lot less. I mist it everyday.
One factor could be the lighting. I switched to using a 75watt infared bulb instead of the day light and moon bulb. It was just too much of a hassle switching the two in the morning and evening. So now she just has the infared bulb on all the time. It helps with keeping the temp constant.
Could this be contributing to her decreased use in the hide?
