No, it seriously was not that. We didn't refuse to vote for Harris because of the idiotic cats nonsense. It was in large part her and the whole DNC's explicit embrace of DEI (note: "i don't like DEI" isn't anti-minority. Plenty of minorities also want to get jobs and admitted to schools because they qualify for and earn those things and not as a free handout because of their skin).
Not 20 years ago, like 90% of Americans would have agreed that it's insane to use racial quotas and different standards of qualification for different groups. Today, the 20% or so who disagree with me on that have dragged the DNC into this unpopular position, abandoning a lot of their previous voters. This has consequences.
