A while back someone was working on bringing the animal models over from far cry 3.
There hasn't been any news of progress. I would like to have the animal models from Cabela's Dangerous
Hunts 2013 created for Garry's Mod. The game is an average title but the animal models are actually quite nice.
Cabela's Dangerous Hunts 2013 uses the havok physics engine.
Also, this game needs an african lion!

Dunno if this helps, but there's a big Skyrim pack for GMod out there if you're in need of some animal models.
