This is the Congressional Budget Office Cost Estimate as ordered reported by the House Committee on Natural Resources on September 18, 2019. From the Document: "Current law prohibits the import, export, purchase, sale, transport, and acquisition of big cats, such as lions and tigers, across state lines or the national border. H.R. 1380 would prohibit the breeding and possession of those animals, although wildlife sanctuaries, veterinarians, colleges and universities, zoos, exhibitions, and other entities that meet certain requirements would be exempt. In addition, people who already own such animals would be permitted to keep them if they register with the U.S. Fish and Wildlife Service (USFWS)."
