Due to the changes Animania makes to cows (completely revamps them and sets them as a different mob), it is incompatible with this mod. This should probably be rectified in future versions.

On a side note, a creative item that allows for instant completion of a ritual would be nice.

Well, you can enable vanilla animals in the Animania config...

Or you could add compatibility with Animania cows.

Wouldn't it be cool if there was an 'EntityDictionary'?

Yeah, could be useful for cases like these ^^
