What do you recommend for measuring room humidity? I worry because I have her enclosure in the same room as my chinchillas. The chinchillas require constant AC so I'm sure the humidity isn't the highest (although it's a basement so I'm sure there is still a decent amount even with the AC on). I've just been misting the tank and draped a wet towel over the top to try and increase the humidity. My petco guage does say it's 55-65%, but I realize that's most likely not accurate (and when I mist the humidity gauge goes up to 80%).
Also, I found her out this morning completely stretched up along the side of the tank with her nose at the screen, and she just sat there.. is that normal, or is something wrong (like her trying to get to the heat source)?
