Update:
I promised to update as time went on, so here we go.
I still like Herptopia for the fact that it isn't as chunky as Reptichip and because it arrives expanded and dry.
But I have found one issue that is both a positive but also a negative for me. It is fluffy and doesn't compact down, which is nice.
However, because it is SO fluffy and light, the heavier snakes tend to push it around and aside and then lay on the bare tub. My smaller snake doesn't do this, though.
So I have decided to try something else. I've mixed my Reptichips with Herptopia. About 50/50. (I already had a brick of Reptichips expanded in a big container) I'm hoping this combination will perform better for me. So far, I like it.
I'm just going to have to expand a brick of Reptichip and mix it with Herptopia. And then let it dry out for a few days before using it.
If anything changes, or I run into problems, I will update
Oh, btw. If I should be so lucky to end up with hatchlings, they will probably be on Herptopia, rather then the mix.
