Ah I've been meaning to go and get a thermostat as soon as I'm able to afford it! I purchased the velcro thermometer and humidity gauge without knowing how inaccurate they are, but at least I have some temporary way of gauging if the temperature or humidity is way out of whack. Also been thinking of a new heat mat, since this one came with her, and while it does work, feels like it might not be warm enough. I'm reluctant to get one that's too hot, though, because she does like to burrow and will lay right on the pad, which has been fine so far because it isn't super hot. Not like I can really discourage burrowing.
