7 U.S.C. § 399 — Domestic raising of fur-bearing animals; classification

(a) This section says that fox, rabbit, mink, chinchilla, marten, fisher, muskrat, karakul, and any other fur-bearing animal counts as a domestic animal — but only if it is raised in captivity, for breeding or some other useful purpose. (b) These animals, and anything made from them, count as agricultural products. (c) Breeding, raising, producing, or selling these animals or their products — when a producer does it — counts as farming. These rules apply whenever Congress, the President, or a federal agency classifies or administers a law, order, or regulation that touches these animals.
