i think my snake likes being in a pillow case. also for warmth, if it's cold out, i use cornbags with my herps. basically i buy popcorn kernels, sew them up in a cloth bag, and it's like a microwavable heating pad. you microwave it for a couple minutes and it stays warm for a long time. but it can get really hot, so i let it cool off and take the temp of it before putting my herps near it. anyway, just a useful tip
