My 18 pound leopard, Scarlett has to be inside for winter. I have a tortoise room that is kept at 80F. Her enclosure is on the floor with Coir and coco husk substrate. She has a basking area with a 125 MVB and 100 watt incandescent. I have had to raise them high enough that when she sits there it is not burning her shell, but I don't think she is getting warm enough this way. She spends a majority of her day under the lights. What are my options to heat this area up more without completely drying her shell? Would a heating pad attached to the wall help? The substrate is 8 inches deep in this corner. Thanks for any ideas.
