I don't worry about her. I don't recommend people to let their leos roam free, but Giovanna isn't a "gecko". She's a very slow animal. If you tape her leg to the floor, she wouldn't notice it. Not that I've done it, I'm just explaining her slow reactions. I've only been bit once, and it was recently. I tried putting a leash on her, and she didn't like it. She's never clicked, or chirped in her whole 1 1/2 years of life. She makes this... mmmm sound. She makes it for no reason sometimes, or if you're 'loving' on her she'll do it. It's loud, like a motor. She'll be watching TV with you and you'll hear her randomly mmmmm. I don't know quite how to explain her... Everyone who's come in contact with her has been astonished. She knows her name, and if you call her she walks over to you.
Now before anyone freaks out about my letting her roam free. My house is 100% gecko proof. Lol. Before i let her out, I put towels under all the doors I don't want her going under, and put up a baby gate into the kitchen that has plexi-glass attached to it. She can't walk very fast even in a full sprint, so I don't worry about her getting out. Even then, she's an albino and 'speed walks' under the couch or to the nearest dark place when I open the front door.
Many times I'll be going to the bathroom and she squeezes under the door and comes in and looks at me like "whatcha doin' mama?" and then stands on my foot.
She's truly a unique individual. I don't believe you can give human qualities to a reptile, but she is far from being just a reptile. My Lucie, I wouldn't ever dare giving her GiGi's freedom. She'd escape, or go missing in the house.
I made fabric ramps to the top of the window sill for her, and to the living room window sill. Her favorite place is laying half under the bread basket in the dining room (head in the shade of it) and her body covered in sunshine. I know that if I call her, I'll hear her mmmmm and I can easily locate her. She's a very predictable gecko.
With that being said, I'll continue to say I don't recommend letting your reptiles out to roam the house without close supervision. GiGi will always, and I mean always, be the only exception in my eyes. No one would understand unless they actually met my little retard.
