Jennifer Young-Watson, with help from Antigone Means, has set up the
International Hedgehog Registry, to try and help track all pet hedgehogs.
Here's an excerpt from the registry information:

   This registry is setting out to register all the [pet] African Pygmy 
   Hedgehogs.  We want to do this to a) take a census of all the Hedgehogs 
   that are out there b) to cut down on unwanted inbreeding by unknowing 
   breeders and c) to help track behavoral and genetic traits. 

This is a great chance for your pets to help add to our knowledge about
hedgehogs, so please do register.  Registration is free, although for $10.00
U.S. they do provide a really nice registration certificate, should you want
one.

You can get more information, and register online at their web page:
