Back in 2014, the Guardian ran a piece on the resurgence of the African pygmy hedgehog as a popular pet. As adorable as they are, the author, Hugh Warwick, makes several excellent points as to why this is not a great idea. Paramount among these is the tendency for owners to tire of the critters and set them "free" into a terrain that is not natural to them, and also already a habitat at risk for the rapidly dropping European hedgehog population.
Here's Hugh Warwick's site on how to work for the good of hedgehogs everywhere. Have fun on Hedgehog Street. (Be sure to read their page on hedgehogs and culture!)
