So many of those people treat their cat like a lamp though. Of course your cat is a "loner sociopath" - if you barely interact with it and never give it attention or enrichment it's going to fuck off and do its own thing without you.

A lot of people legitimately think cats are loner sociopaths.

That says more about the people who think this than cats.

So you need serious scientists to spend time, resources and money on a scientific study so you can tell cat haters "Gotcha. I told you so!"??
