The small additional heat introduced drives out moisture -- unless you get confused and leave wet rags in your safe!pisgah---Where does the moisture go when its light inside?
True the RH will go down, but not the total amount of moisture present. I use a light bulb to ADD moisture to my rust blue chamber by putting a wet rag close by. The added heat of the chamber will take more water from the rag.
If you decide to use the cat litter I would use a DampRid container since its the same concept. Just poke holes in the lid.

Any recommendations what container to use to put it in when putting it in my safe? I want something that I don't have to worry about it spilling if it turns over. Ideas?
As far as I know all that a higher atmospheric tempererature does is to allow a higher moisture (water vapor) content. The moment that micro-atmosphere cools off (should the light bulb go out or the door stands open for a while) that water vapor condensates.... etc.My thoughts on silica gel dessicants in gun safe -- unless the safe is hermetically sealed, it's drawing in moisture from the outside and you will end up with higher humidity inside than out. Installing a low-wattage lightbulb is a better idea, IMO.
