How Louisville Handles Animal Ordinances: A Practical Guide
Louisville maintains 145 local ordinances across all categories, and 11 of those deal specifically with animal ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Louisville falls on the strict-to-permissive spectrum compared to other cities.
Wildlife Rescue Permits
Louisville Metro bans keeping wild or exotic animals, but authorized wildlife rehabilitators holding a state-issued permit are exempt from the ban.
