It should be noted that the Humane Society has been campaigning to have reptiles banned as pets for the last decade or so. :P
Many places do not recognize reptiles in their animal cruelty statutes, so you may not have any recourse... I would start by calling local animal control and see where they point you to. City police and the RCMP might do something. Health department might do something. They'd all be better than the Humane Society... which though well intentioned, generally do not have the facilities or knowledge to adequately judge reptile cases.
There is a fine line between a hobby and a mental illness.
