Of all your post this is the one line that gives a reason not to be cruel to animals.
(please note that I am playing devil's advocate here. I've owned up to 21 cats at a time and always treated them exceptionally well. )
Animals are not human. They are at best property.
We are required, however, to be good stewards of what God has given us.
So the question arises, How does my duty to be a good steward of what God has given me, overrule my neighbors right of freedom to do what he wants with his property?

If you don't know the difference between a shovel and a domestic animal, God help you.
