Laurie,
We use the repti-fogger, you can buy it at LLL. We have had great luck with them, we have a few on the adults and the babies as well. I use PVC piping to get the fog to go over the cage and then I drill 3 small holes in it so it falls like a waterfall effect, it seems to work better for them, also some condensation accumulates on the screen from the fog and they like to drink that as well. Both of our adult males are WC so we are not sure how old they are exactly, however this guy was very small when we got him and now he has grown to an even larger size then our other adult male and has taken over as the dominant one, they are not housed together anymore. We could at one time have multiple females and the two males in an enclosure but now we keep them separate. As far as being comfortable, both our males are extremely docile and friendly and will eat out of your hand, however we are seeing that the females are a bit more skittish and prefer to be left alone, my wife was able to get our very young new female to eat out of her hand, since we have put her in with the other female, she seems to be doing much better and likes the company. Funny thing is, you can tell the temperments in the babies too, even the one female that we have left, she is the shyest and won't eat if you are looking. We are fattening up the little male that we will be sending to you next week, you will love him, just remember to keep plenty of food around they are eating machines...
