In my city, its illegal to keep any reptiles of any kind. I got a copy of the by-laws concerning animals from City Hall to make sure I always had my butt covered concerning my dog but as I read through all of them, it clearly states that its illegal to own any reptile or anything considered "exotic" which they go on to list.
My neighbour's son had a turtle and when the Animal Control came to her house to take a statement from her concerning another neighbours animals, they saw the turtle and removed it from the home. Maybe it depends on who the animal control officer is............I just keep my mouth shut about most of my pets.
Sarcasm is just one more service I offer.............
