Another leachie anon here. Mine is a poop monster. If handled long enough, he will inevitably projectile shit all over the place. His favorite place to shit is on his glass door, forcing me to get up and clean it before it leaks on my floor. >>5061709
The enclosure looks moderately difficult to climb for a gargoyle.
You're right to worry about cohabitation after coupling. Gargoyles are notorious cannibals; someone is very likely going to lose a tail, so be prepared for that.
Be sure to keep multiple locations for food to discourage resource competition.
Before cohabitation, you can trade out pieces of bark or what have you to get them accustomed to the others' scent.
