I've read here about setting up the config to control mob spawning: http://mocreatures.org/forum/m/13290502/viewthread/20794777-to-few-moc-creatures-spawning

I downloaded Mo'Creatures for 1.7.10 and I don't have a "EntityBiomeGroup.cfg" in my config folder or in any sub folder in my config folder. I also don't have a CustomSpawner folder in my config folder. I have a MoCreatures folder in my config folder, and inside that folder I only have a MoCreatures.cfg file and a MoCSettings.cfg file.

i guess mo'creatures wil create these files as soon as necessary. were you already ingame with such a biom loaded?

I got a reply from their site, apparently you need the custom mob spawner mod in order for those files to appear.
