good idea! One other thing though I' take extra caution and insulate/waterproof around the tiles n flexwatt to prevent any possibility of a shock/short if a water bowl spills or they take
a wee on it....Marks animals are outstanding! You are in for a great experience. I've been building a nice group of his cinctums the last couple years and am just blown away by thier color n health...if I can say one thing that really shocked me about heloderms compared to most reptiles is they like it cool...keep um an area around 88 but if they are too nervous or puke on ya turn um down a couple degrees, and off at room temp at night...think the digestive system can get to working overtime on these guys....Also babies really like plenty of snug hiding spots like paper towel rolls and seem to benefit a lot from a humid hide once they start growing like weeds and perpetually shedding the first two years or so... good luck
PEACE
