Iowa prohibits private possession of big cats. It is unlawful to own, possess, or breed dangerous wild animals and Iowa classifies all cats, excluding domestic cats, as dangerous wild animals. Any person who possessed a big cat prior to July 1, 2007 may continue possession with a permit. Permit holders must meet enclosure and care requirements and pay an annual permit fee ranging from one hundred to three hundred dollars depending upon the species. Some institutions are exempt from this prohibition, including AZA-accredited institutions, wildlife sanctuaries, research facilities, cities, or circuses holding a temporary operating city issued permit.
