This is the page that restricts snakes, I doubt that they will care if it is dwarf, super dwarf or full size... If you are a breeder with a business it looks like you can get a permit to keep one.
I will defiantly keep you up dated. I love them but I cant do the whole 16 and 18 foot snake thing at the moment so that's why i wanted a super dwarf they only get 6-8 feet long.
