Is it legal to own a ferret in Illinois?
The short answer
Ferrets are legal pets in Illinois and owners need no permit. They are not on the Dangerous Animals Act list and are treated as domestic animals. The one wrinkle: anyone who breeds, raises, or sells ferrets must first obtain a game breeder permit from the Illinois DNR under the Wildlife Code (the Class A noncommercial version is free).
What Illinois law says
720 ILCS 585 (Dangerous Animals Act) does not cover ferrets, and 520 ILCS 5/3.23 of the Wildlife Code requires only breeders and sellers of ferrets — not pet owners — to hold a Class A or Class B game breeder permit.
Which agency regulates ferrets in Illinois
Illinois Department of Natural Resources is the authority for ferret (Mustela putorius furo) possession in Illinois.
Is there a permit for pet ferrets?
No permit is required at the state level. A Class A (free, noncommercial) or Class B (commercial) game breeder permit is required only to breed, raise, or sell ferrets.
Penalties and enforcement
Breeding or selling ferrets without a breeder permit is a petty offense under the Wildlife Code; simple ownership carries no penalty.
Local city and county rules
Chicago and other municipalities apply their own animal codes, so verify locally.
