Nope. Cats have been proven to consistently meow or vocalise in a different way to humans than other cats. So they know the difference.

Cross posted from here where it’s discussed that this is mostly untrue. https://feddit.uk/post/33710607

They don’t think we’re incompetent cats. They know we’re incompetent humans.

We think one of our cats thinks he’s a human, whilst believing his sister and two brothers are still cats.

“Mama! Papa! one of those cats is trying to get into our bedroom and sleep on our human bed for humans”

I sort of knew I was incompetent as a cat, but hearing that my cats agree with it is pretty harsh. It tracks though.

Bullshit! My cat definately knows shes superior to a human

Well both are right…

This seems interesting, source?
