Okay Rick, I'll just have to wait and see where they go before I make my move. I have read however that it is typical for them to go in one corner (better than my beardie that went wherever he pleased).
10dor1fro32 thanks. I was under the impression that the light was to be used at night when the gecko is active. I guess not. If the heat pad is warm enough for the vivarium, is there any need for me to get a bulb? I'll probably just get one in case though. And about the carefresh: I read that it can get really dusty and smell bad if wet, but other than that it's great. I don't know, I guess I'll just have to try out the different types until I find what's right for me and the gecko. This will be my first time using a substrate other than sand and soil for a lizard. I think once I get the "potty training" down, that'll make it a heck of a lot easier.
