I've noticed that all three of my Leos have developed habits that are both amusing and a bit frustrating. I thought I'd share my geckos habits, and hopefully you can share yours. 
My Chinacat loves to dig. She loves to dig so much she'll dig all the substrate out of her humid hide, and dig all the calcium out of her dish. I have to clean her enclosure a lot, and she won't let me clean and leave her in the enclosure. When I clean, I have to pick her up and let her sit on my shoulder. I think that's why she makes the huge messes in her enclosure, just so she can get more shoulder time.
I moved my girls into 10 gallon tanks with a repti-hammock up in a corner, and branches to climb up to the hammock. Both girls have decided that their hammocks make the perfect bathroom. While this makes cleaning their poo a breeze, it's the first thing you see when you look in their tanks!
Even my little guy has developed an icky bathroom habit. Egnima likes to go right next to the waterdish. I tried moving the dish, and Egnima still goes right next to the dish. That's not sanitary. Gonna try changing the water dish to see if that will discourage the little guy from going right next to it.
