Now working for updated game version 1.4 - Contains the entire animal overhaul. If you only want to use Safari Mode, you don't need this- it's integrated into Safari Mode.

An updated version of Animal Overhaul that allows you to place Arctic and Timber Wolves together without them fighting each other. Includes both base game and Arctic DLC with all features of AO. If you don't have arctic DLC, use version 1.1 of the mod.

Updated on 5/15/2020 for PZ 1.2 South American release. This includes everything you need for any combination of pack ownership.
Enjoy.

Working for latest game update 1.4. This covers changes for arctic animals including dall sheep/reindeer walk-ins, feeding costs adjustment, and polar bear space reduction. (See forum post for full details.)

Working in latest game update 1.4. Safari Mode includes Animal Overhaul but you can safely switch between them. This turns the game into an African wild animal safari experience and will not work well for 'regular zoos.' Try different saves/mod combos!
