(2) Whoever intentionally releases an animal that is lawfully confined for companionship or protection of persons or property, recreation, exhibition, or educational purposes, acting without the consent of the owner or custodian of the animal, is guilty of a Class C misdemeanor. A 2nd violation of this subsection by a person is a Class A misdemeanor. A 3rd or subsequent violation of this subsection by a person is a Class I felony.

(2m) Whoever intentionally releases an animal that is lawfully confined for scientific, farming, restocking, research or commercial purposes, acting without the consent of the owner or custodian of the animal, is guilty of a Class H felony.

(3) Subsections (2) and (2m) do not apply to any humane officer, local health officer, peace officer, employee of the department of natural resources while on any land licensed under s. 169.15, 169.18, or 169.19, subject to certification under s. 90.21, or designated as a wildlife refuge under s. 29.621(1) or employee of the department of agriculture, trade and consumer protection if the officer's or employee's acts are in good faith and in an apparently authorized and reasonable fulfillment of his or her duties.
