It's okay to have some sort of climbing wall in their cage. Some love to climb, but make sure that there is nothing rough or sharp underneath them that they can fall on. Believe it or not leopard geckos are clumsy.
Always have a top on your cage. That top has to have some sort of ventilation in it. If there is no ventilation in the tank then you gecko will probably die.
If if there is any type of hole in your tank, than its probably not all of that safe. A hole in the glass can weaken the tank and if you put any weight in it, the tank will shatter. You also want to make sure that if you have any pets like dogs and cats, you want to make sure that they can't get in.
You should have some sort of coverage over the heat pad underneath the tank. You can either put paper towels or carpet, NEVER EVER USE SAND IN YOUR LEOPARD GECKOS TANK. Paper towels I find are the easiest to clean and my geckos love it. Don't use pebbles, sand, and I don't recommend bark but some people use it. Geckos love to hunt, crickets are great to give them exercise, and nutrients. NEVER put more than 5 crickets in your tank, if your leopard gecko doesn't kill them before they swallow them the cricket could eat threw your gecko and kill your gecko. (Make sure that any cricket that you have put in to your leopard geckos tank has drank water and has been fed). You have to feed crickets before you feed them to your gecko or sled they will chew on your geckos skin while they are sleeping. These at the things you can use to feed your crickets and give them water
