The Legality of Owning a Sulcata
Some species of tortoise are protected animals. You can get into legal trouble if caught with an animal that is not allowed within your region. Most wildlife tortoises are protected, but you can get the captive variety by breeders. However, all Sulcata tortoises are legal! Most are captive-bred and legal to acquire in many states in the US.
If you are doubtful about the legality of your choice of tortoise, consult relevant authorities in your locality. One place to ask about the legality of owning a tortoise as a pet in the US is the United States Fish and Wildlife service. There is an approved adoption program you may want to know more about.
Despite tortoise groups and government agencies averse to captive-bred desert tortoises, breeding is currently legal in the US. Considering the possible size and age of adult Sulcata tortoises, it is best to consider your ability to care for and house such a large animal.
