Can I just let it roam my house? I’ve figured any type of tortoise will be fine with just a heat mat..... not need for those expensive UVB lamps!Open top cage with sand and lots of heat so it just like their natural habitat. Moisture will cause the shell rot! I also hear I can feed them my scraps from dinner any truth to that? Also give me the 5 best brands of lights and 12 places each where I can buy them!
