I've decided to build a snake rack to save some room because my collection is expanding rapidly. I've picked up 5 new snake this week alone. I plan on making it out of wood because its light. My question is what should I use to heat it? I keep hearing about flexwatt but I've read you have to solder it & wire it. I took electrical in high school so the wiring is no problem but I have no idea how to solder, & id have to go out & buy the supplies needed to solder. Would it be a bad idea to use flexwatt with wood due to a risk of fire? Is there anything else I could use?
