I dont 100 percent know what your asking, but if your asking what you need for your leopard, you need to buy 2 hides for each end. You can get some fake plants to put around. The cold and hot side is when you put the heat lamp on one end of the cage so one side is hotter than the other. You will need to get the temp on each side and compare it with the numbers people will give on caresheets. Its like 90 on the hot and 80ish on the cold..check that though im not to sure bout that. I have a 15 gallon tank for mine and i use a 50 watt bulb which gives me the right temps. For a 10 gall it might be slightly off but good luck with your leopard and tank.
