I think people who grow up middle class in a first world country are so sheltered from suffering that animal cruelty is the first example of it that they can actually empathize with and understand as a black and white issue (to them). Unfortunately, suffering is just a fact of life for everyone but the most privileged. The logical conclusion to “if you can’t give animals the standard of care that I expect as a global top 1%er of wealth, then you shouldn’t own any pets” is a PETA type policy of killing any pet that is living a suboptimal existence. Which, if they were humans, we would consider that genocide. It’s really just not a reasonable stance at all.
