First of all, I would like to say that I don't place any blame on Matt. I think what happened here was a simple and honest mistake. He really did show no signs of being male, I didn't know that it couldn't be definite, and I don't believe that Matt/Ace Reptiles purposefully sold me a female knowing that it may not be female. Also, Matt has been very helpful, which I really appreciate.
Kirsten simply waiting to see if she lays isn't really something I see as an option as if she does lay eggs, I need to have equipment ready. So I'm getting that together now, even if she turns out not to be gravid, I'll at least have things ready for if I breed next year, which I am considering. But it is now the waiting game to find out if she lays or not.
Marc, I've PMed you. But as I said to Kirsten, simply waiting without preparing at all isn't really an option as I'm not prepared to just get rid of the eggs, I love geckos far too much for that!
As Olivine said, the reason why it does in fact matter is that I could be faced with a way under age gravid female. So yeah, it does matter a lot. But here's hoping that it's just fat deposits and that she's just not hungry due to the cold climate lately. If it's not then I'm going to be prepared for eggs just in case and will be doing all I can to make sure that she gets calcium and everything she needs so it does as minimal damage as possible.
