People care less for animals if threatened by vegetarianism
A study has found that people who view vegetarianism as a threat to their way of life, and those who believe in human supremacy over animals, are likely to have fewer animal species that they view as worthy of moral consideration (compared to people who do not see vegetarianism as a threat or who do not believe in human supremacy over animals). Moral attitudes varied strongly towards different animal species, for example, 90% of participants a felt moral obligation to care for the welfare of dogs, compared to 51% who felt the same obligation for pigs.
