The United States Department of Agriculture will not grant a license to keep a pet tiger unless the animal will be used for commercial activity such as breeding. Under the provisions of the Captive Wildlife Safety Act, tigers cannot be transported or sold as pets across state lines.
In addition to federal laws, states have their own requirements that must be satisfied for a tiger to be kept in captivity. Tigers are not well-suited to life as pets. They are large, potentially dangerous, and have been known to kill their owners. They need suitable cages or safe enclosures. They require large amounts of raw meat as food, as well as opportunities for play and intellectual enrichment. Finding a veterinarian who will treat one can also be a challenge.
