I thought I would give a little insight into a hedgehog for those readers from Countries like OZ, that do not have these beautiful little creatures, and most would be very surprised to learn that you could have one as a pet.
Hedgehogs are found through parts of Europe, Asia, Africa, and New Zealand (by introduction). There are no hedgehogs native to Australia, and no living species native to the Americas (although fossils of at least four extinct species were discovered in South America). Hedgehogs share distant ancestry with shrews (order Soricidae), with gymnures possibly being the intermediate link, and have changed little over the last 15 million years. Like many of the first mammals they have adapted to a nocturnal, insectivorous way of life.
The purchase of Domesticated Hedgehogs has seen a considerable increase in the last few years, owing to their apparently innocent and playful looks. Hedgehogs are considered a low-maintenance pet. Their curiosity and need for stimuli make for quick adjustment to their owners, and their eating and waste habits make for a relatively clean housing environment for the pet. Overall they exhibit very few vulnerabilities to species-specific disease (although several do exist) and are easy to care for.
