Males tend to fast as a relation to the breeding season. If you have stand alone tanks it tends to be more of an issue, although it happens with most ball pythons. The main reason being that most breeders use rack systems and tend to maintain ambient temperature in the room higher than most who don't use racks. You can have a hot and a cold side using a uth or flexwatt but it is harder to keep the ambient up with the more height you have to the cage. If your cage has more height, then you are relying on the uth to heat the whole space and it is asking a little to much. As a result, your ambient temp in the cage drops unless you keep the room at a low to mid 80 degree range. When that ambient drops, that triggers their breeding season and they shift their focus. It is important to note that your hot and cool side can stay the same, but your ambient can drop. You can circumvent this a little bit easier with a closed rack system because they are very low and retain the heat very well. You can also do it, as I mentioned, by keeping the ambient in the room up. hope this helps.
