Good points about gutloading and dusting Wally, I forget that since my snake friends all feed frozen and don't deal with any of that.
If you are serious and all this sounds good definitely look into the book "The Leopard Gecko Manual". Last time I checked it was less than $5 at the store. Even the most experienced here refer to it from time to time.
Also when the gecko reaches maturity it will pretty much tell you that you need to feed less. Freaks most first timers out, even me, my girl just stopped eating one day. That's when you can go to less often feedings.
Please, ask as many questions as you like. We are very happy to answer any and all, the rule around here (at least to me) is we will happily explain in any detail anything BEFORE you get an animal. We also will help afterwards, but we like to see as many potential problems and questions offset before you have the animal.
So, ask away, and if you join us in the leo world, you won't be disappointed. They are the hams of the lizard world, I have yet to meet one without a crazy habit or funny quirk and they are easy to handle, care for, and well maybe I'm biased.
But can you resist this face? I know she's up to something...
