its a mod that Improves the AI of the Animals, i remember the images were Sabre cats fighting wolves and hunting, i can be more precise since i never really paid atention till know but now i cant find the mod
it was in the Nexus list of the Top Mods of all time but now it isnt.
its not Bellyachus( think its the name,sorry if its wrong )that mod only changes the textures, also there was other that added to the game puppies and little goats and rabbits if you can help me find that too much appreciated
Thanks for paying atention

I believe the animal AI mod you're looking for is SkyTEST, which creates a more natural animal AI set.

Thanks
