From the Document: "Current law prohibits the import, export, purchase, sale, transport, or acquisition of big cats, such as lions and tigers, across state lines or the national border. H.R. 263 would generally 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). For this estimate, CBO [Congressional Budget Office] assumes that H.R. 263 will be enacted late in fiscal year 2022. The bill would direct USFWS to issue regulations to implement the prohibition on breeding and possession. In addition, CBO expects that under the bill, the Department of Agriculture (USDA) could revise existing regulations on the licensing of entities that possess, exhibit, and breed big cats. Based on the costs of similar tasks, we estimate that developing those regulations would cost $1 million over the 2022-2023 period."
