Jo-anne depending on your area where you live and the normal humidity sometimes it can be difficult to keep the humidity up in the cage. I live in a dry climate and with the airconditioning in the house it was difficult to keep it where I wanted....so I invested in a Repti-fogger by zoo med. It is very easy to use and maintain. I use a zoo med hygrotherm which is a humidistat and a thermostat and you can plug in the fogger and a heat mat if you want and it keeps your temps and humidity exactly where you want them. You can also program it for day and night settings. Petsmart or Petco sells the Repti-fogger but usually you have to get the hygrotherm from a reptile store which sells from $70-$100 US.
