I get a lot of e-mails and phone calls when temperature begins to fluctuate, especially during the Fall and Spring months. It seems that hedgehogs are not really happy when the temperature isn’t fairly stable for them. It can really stress them out and lead to things like quill loss, grumpiness, loss of appetite, weight loss and more serious things such as respiratory infections and attempted hibernation.
Hedgehogs enjoy burrowing down into their bedding. If you think about it, a heated pad under the cage is the most natural way for them to get some extra warmth. In the wild, hedgehogs burrow down to a temperature that is comfy for them. In captivity, heated lamps or space heaters are not the best solution for heat. The heat is more difficult to keep stable and hedgehogs do not go out in the sun to bask like reptiles. For that reason, heated lamps are best suited for reptiles.
In the wild, hedgehogs are out and about during the coolest part of the day. It can actually get chilly in their natural habitat during the nighttime. For this reason, I feel it is important to create a warmer sleeping spot. If you place a small animal heated pad under their igloo, they will really appreciate it.
I recommend the K & H Small Animal Heated Pad.
