Its illegal to even own them in most US states, but not in the UK. If you go to places like Brixton Market in London you can buy them (to eat!) and some people go there to buy them to 'rescue' them. You can buy them in the UK from pet shops or specialists, but to be honest when they breed owners can end up with so many you are glad to give them away. I have four, two that I was given as tiny babies, about as big as your small finger nail, and now the size of tennis balls, and two that I took in as 'rescues'.
