What Are Some Disagreements in the Area of Animal Welfare?

I'm going to facilitate a Double Crux workshop at an animal welfare volunteer training day. If you're not familiar with Double Crux, then here's a blog post about it. Very briefly, it's a method for resolving/understanding disagreements and consists of steps such as defining terms, determining premises, seeking crucial considerations, etc.

I'm looking for topic ideas of disagreements in the area of animal welfare. What are some topics where you think currently the largest disagreements are? My current guesses are these, for instance:

• Clean meat vs alternative meat products
• Whether promoting vegan diets is the most effective intervention
• What the moral difference of non-human animals vs humans is
• Pragmatic vs abolitionist approaches

Do you have any ideas to share?
