Can't wait to see the finished product. So, if you leave it to dry, and de-fume. Will it be non-toxic to the geckos. I want to do something like this, but don't know if the leos lick the rock or something; there could be health issues?
Licking shouldn't be a problem when fumes are gone, but it'd be wise to get a non-toxic sealer.
More pictures.
A bit wobbly currently, should change once glue, supports and grout has been applied.
Also I'll have to get something to screen that grid, I'm a bit worried gecko toes could get stuck in there, air shouldn't be a problem since the top has a grid as well.
