MT - Exotic pets - Chapter 4. Commercial Activities.
Summary: This set of Montana laws covers both "roadside menagerie" (any place where one or more wild animals are kept in captivity for the evident purpose of exhibition or attracting trade, excluding an educational institution or a traveling theatrical exhibition or circus based outside of Montana) and "wild animal menagerie" (any place where one or more bears or large cats, including cougars, lions, tigers, jaguars, leopards, pumas, cheetahs, ocelots, and hybrids of those large cats are kept in captivity for use other than public exhibition). The latter definition seems to cover the keeping of those listed species as exotic pets. Under the section, it is unlawful for any person to operate a roadside menagerie or wild animal menagerie without a permit. The annual permit fee for five or less animals is $10. The annual permit fee for more than five animals is $25.
