They aren’t under any heat at the moment. We use a heating pad in there sleeping cage because we find it safer. So if they are hot they don’t have to be under it which they generally arent because where we live isn’t cold. During the day they are outside in their pen or with me. It was really hot outside today so we only went out a couple of times and I could tell they were hot. But inside they are in the air conditioning and the other seems to be just fine with that. They are sleeping on me at the moment and it seems fine but i can hear it making a noise out of its nostrils. It’s sort of like a popping sound.
