The Financial Times had a nice article about high-end habitats for pets the other day. One example was the Cool Pet House by Funky Pets in Australia. It comes equipped with air conditioning, heating, humidifier, LED lighting and, as an option, a wireless webcam so you can keep an eye on your friend from your own house or over the internet. All electrical equipment is 12 volt only to be safe. Seems only to be sold in Australia so far however.
