what is a good night time temp of them

My temp sometimes goes down to 65F and it doesn't seem to affect him at all. All is normal. If you look at current weather at the location of your Uro, you'll notice nightime temps get to 50-60F at this time of the year. Keep in mind that they are usually found in burrows but I would assume they aren't deep enough to stay warm for long.

My u. geyri seems to he happiest (activity level, appetite, energy) at higher nighttime temps 75 - 85.

I think this issue is somewhat debatable but allowing temps to drop as low as 50-60 seems a little extreme.

Below 65 I'd think about activating your heat. Beyond that and you'll start seeing respiratory/infection problems.

I agree that 65F is good. That's about how cold it gets in my place. In the summer it may get warmer. I wasn't saying to go to 50F. Look at the weather in the Saharah and you'll see 55F at night. I didn't recommend to take it to that point. I was just letting you know that you don't need to heat 24hrs.

Does the temp inside the borrow cool to the ambient air temperature during the night?
