So I've noticed at a few points for the past couple months that the scales on my ball python's belly have felt a little rough in a few places. When I look to see what the issue is, I see nothing. Her belly is the normal creamish color with little black stripes, but there's nothing else there. It's not pink or any other color; it just feels ROUGH in a couple places. The only thing I can say is that one spot looks a little flaky, but that's it. I tried to take pictures but it looks like nothing, it's something you have to feel to notice. I also used a heat pad on a thermostat, and both have been a little wonky lately. The heat pad doesn't warm up like it used to-when I place my hand over the glass, I can BARELY feel it-and the thermostat had been working weird and finally sparked on me last week, so I ordered a new one and stopped using the old one. I don't know if maybe these rough places are just very mild burns?

This time of the year has been a little rough as far as humidity (we're talking winter in Minnesota, so pretty dry), so sometimes it's a little low for a ball python. I try to keep it at about 60, but during the night and when I'm at work or in class, it's dropped to as low as 30ish-which I fix immediately by spraying the enclosure with warm water, and for the rest of the day, it's at the 60ish mark. Could it be possible that her scales are a little dried out? Again, I tried taking pictures, but it looks completely NORMAL. She's also been eating fine, had a shed last on March 20th (which came off all in once piece), and has been behaving normally, if not a tad bit more active now that she's used to her surroundings.

Any and all thoughts are appreciated. I'm torn on whether to be concerned or not; again, everything about her is completely normal except for the few rough patches on her belly.
