Thanks a lot guys!
Hehe, thank you Derek, but I'm not quite sure if there's much 'mastery' going on here

I have paired up three pairs this year. The oldest female has had two different males with her at this point. I really haven't seen any action with any of these pairs, so I'm not waiting to see any babies this year. I might try other males with the other two females as well, haven't decided yet.
There's a tiny little chance that the oldest male got some tail from the oldest female, but can't confirm that. He did chase her like crazy at one point - like he usually does - and there were some days that their tails seemed to intertwine, but they were hidden, so I'm not 100% on that.
To make matters more exciting, said female has been eagerly seeking the hottest spot in her terrarium for a while now. Trying not to overheat, she's only had 25W spotlight, but she wasn't happy until I changed it to 40W. Now she mostly rests on the hottest spot and refuses even small meals. She hasn't gotten any more plump and she's always been a bit iffy about feeding in general. So who knows...
There's another male with her right now, but I won't keep him there long, just in case the female decides to go medieval on him.
On a side-note I believe that small litters are a nitschei thing. That is, until proven otherwise.
