Marukan CASA Reversible Heater for Hedgehogs Originally for hedgehogs, but I've also used it for my rabbit after my hedgehog passed away. I think it can be used for small animals. It has a strong and a weak side, making temperature adjustment easy. Due to my mistake, the cord has been chewed on by the hedgehog, and there are some slightly torn areas. The surface is torn, but the wiring is encased in metal, so it's not dangerous. If you are okay with the current condition, please consider purchasing it. ♬.*゜
