I know that the DNR requires black rat snakes to have PIT tags and permits. Does that apply to all black rats? or just WC, or just "natrual" color phase? I've seen white sided black rats for sale in pet shops in ohio and the shop owners insisted there were no restrictions or regulations against them, no permits necessary , etc. Is this just typical pet shop ignorance? Or is it legal to own a captive bred, white sided without a permit?
