Why do you think the use of holistic treatments for animals is controversial?

Holistic treatments within animals is controversial because many people hunt animals for a living which basically makes them immune to lets say having feelings for animals or wild life. Whereas, many people believe the animal "tortures" should be put away for their crimes. Hurting animals and wildlife is against the law in many states in the US.

I'm not entirely sure why holistic treatments would be controversial in animals. Perhaps what makes them controversial is the fact that we tend to assume we know what makes them holistic and how they will be holistic for the animal - this isn't necessarily the case, as we can only make a good guess about it.
