Under Maine law, it is lawful to privately possess big cats with a General Wildlife Possession Permit. Permit holders must meet caging requirements and consent to an inspection of the facilities in which the animal will be kept. Additional caging and facility requirements may be imposed on owners if it is necessary to mitigate safety risks or ensure humane treatment of the big cat. The permit must be renewed every two years at a fee of twenty-seven dollars. Likewise, a Wildlife Exhibit Permit authorizes any commercial display of wildlife. The permit must be renewed every two years at a fee of one hundred and forty-seven dollars. This permit does not allow pet shops to display or sell big cats.
