The short answer is yes, it is legal to own a fox as a pet in Florida. In Florida, you will need a Class III exotic animal license to keep a fox as a pet. Florida Fish and Wildlife (FWC) oversees captive bred foxes/exotics. There are enclosure requirements for outside of the house which your fox will require to be happy.   We always strongly advise people looking for a pet fox to do their research regarding not only city and county ordinances but to also research what it is like to have a pet fox and whether it is a commitment you are willing to get into.
