Most people love to share outrage over abuse of conventional pets or bizarre and seemingly psychotic behaviour of eating dogs yet feel nothing to the slaughter of a pig. It is my opinion that most people ignore and switch “off” at these discussions as a way to maintain plausible deniability. Like people get mad at PETA showing videos on the street of slaughterhouses in a “how dare you” sort of way but really I’m of the attitude of how dare they.
Cows are very intelligent, have long term memories, and feel desolation when their calves are taken away from them. Cats as well. The whole cats vs dogs argument is just mega weird to me and like you say really emphasizes the cognitive dissonance at play in most people who consider themselves kind to animals yet eat meat.
