Sounds to me it could just be because of the season change, and possibly the hormones are a stirrin (esp if ignoring food. A man with a mission doesn't think about food )... could be he just wants to be with his momma , altho if BOTH WTFs are doing it then it's more likely just a seasonal thing imo.

Only other thing I could think of is, when leopard geckos are spending a LOT of time out of their regular hides it turned out 80% of the time to be that their hide was too hot. Is there a heating source near that hide or on the tank that could be hotter than he wants right now? Elevated heat in a lot of herps/amphibs cause them to act out of the norm and get more active or lay in irregular places.
