Hi, I'm an Animania dev, our users are begging for compatibility with Butchercraft. However, to do that, I think quite a lot of work would be needed.

All our animals have EntityAnimaniaCow, EntityAnimaniaPig, EntityAnimaniaSheep or a similar variation as a base class. Some (cows for example) also extend EntityCow, but pigs do not extend EntityPig. Additionally, our animals have genders and different models based on genders. I looked at your source code, and since you're using a hardcoded model for the hooked animals, you would also need a model for every variation of animania animals (16 models only for cows, 24 if you include baby cows). Another approach could be to make the hook model dynamic, but you'd have to figure out how to rotate their arms and legs.

What I'm saying is, is that it's difficult but doable. If you think you want to do it, I'd gladly support you if you have any questions about our code.
