since posting this ive read that tiles are the best thing. Are they better then reptile carpet , due to the claw catching thing?
Should the tiles be a particular material? and should they be as big as possible to maintain a flat surface (ie. not have loads of lines inbetween the tiles)
I use sand. Have never had problems with impaction look in the photos posted. These droppings are from one of my geckos that was around 29 grams and was switched from paper towel to sand. Yes geckos eat sand is it safe for them to be on it, you make the descision.
Gonna steal my husband's example for the sand bit: It's the same as playing Russian roulette -- one more spin of the chamber, and you might get the bullet. You could go years with your geckos on sand and never have a problem, but the chance is there that you could end up with a dead or suffering gecko. When you know the possible dangers, and can so easily avoid them, why take the risk?
