Albert the alligator weighs 750 pounds.
Owner Tony Cavallaro shared videos of Albert and said his pet is gentle and loves people, especially children.
He says he had a license to own the 30-year-old alligator but it expired in 2021.
Authorities denied Cavallaro's request to renew it, arguing the alligator has serious health problems and should not be kept in a private home.
They say a licensed caretaker will look after Albert until they can find a permanent solution.
