Each state has different rules, and may require you to have a special permit for certain animals.

Massachusetts ( less than a mile from my home) does NOT permit you to own an alligator. However, some folks have a permit, like the woman who does the shows at schools, festivals etc. Even she only owns 2 small ones (I guess there are different varieties of 'gator.) Here in RI, ANYONE can own an alligator, of any size. There is a family close to me with 3, the largest over 10 foot long. Been in the newspaper some, last year their abuttors complained, worried the gators would get out and get small dogs, cats, etc.

And don't forget some places (I think Texas is one?) offer "canned hunts." Don't get me started . . . . .
