Her hot spot is 91f and the cool end is 73 I know that's a bit low but it should be fine.. her hide is around 80-83 degrees..I did not prepare the adult mouse she regurgitated petco did as I stated above .. I prepare mice by soaking them in warm water (about 110-115f) for around 40 mins to be safe .. I use a temp gun for both the water and the mouse after he's thawed to make sure it's hot enough
