I'd go with a ceramic heat emitter and thermostat. A heating pad will not keep a wire cage warm enough. Sometimes, depending on the room temperature a heating pad is ok with a bin but you need to keep the whole cage environment at a suitable temperature.
The problem with using a heating pad is, the area directly above the heating pad is very warm. When the hedgehog leaves it to eat or wheel, the air temperature is cooler and is sudden drop in temperature. This is not healthy. What you want is the whole cage environment to be a suitable temperature and a ceramic heat emitter and thermostat will do that.
