Owning an otter as a pet in the U.S. is one of the most tightly regulated forms of exotic animal ownership. While otters have become popularized on social media as playful companions, most states consider them wild animals that require specialized care and habitats—placing them under strict wildlife or exotic pet laws.
 According to 2025 data compiled from state wildlife agencies and the U.S. Fish and Wildlife Service, the majority of states prohibit private otter ownership, while a limited number issue permits under controlled conditions. Only a handful of states—including Florida, Nevada, Missouri, and Tennessee—currently classify otters as legal pets without a permit.
The core distinction lies between native species (like the North American river otter) and non-native species (such as the Asian small-clawed otter). Native otters are often protected under the Marine Mammal Protection Act and state-level conservation laws, making it illegal to capture or possess them in most jurisdictions. Non-native species fall under exotic animal statutes that vary widely by state. In states where ownership is “permit required,” these permits are typically issued for education, research, or exhibition purposes, not casual pet ownership.
Beyond legality, otters present significant ethical and ecological challenges. They require large water enclosures, social companionship, and diets that mimic wild feeding habits—conditions rarely met in domestic settings. Conservation experts also warn that rising demand for pet otters contributes to illegal wildlife trade, especially in Southeast Asia, where wild populations of Asian small-clawed otters have declined sharply.
This dataset categorizes each U.S. state by its current stance on private otter ownership—Legal, Permit Required, or Illegal—to provide a clear national overview of how wildlife protection, animal welfare, and exotic-pet policy intersect in 2025.
