I find this of cats too.

I know a lot of people think they’re aloof and dumb, but my cats know their names, each others names, and several words. You can tell because they hear it and try to ignore it, but their tail wags giving away that they do know what you’re saying.

They can also pick up really specific sounds, like if I pick up two small plates they run over hopping in giving them wet food. Not one plate, not three, not large or medium, only two small ones.

Recently there was an article stating they do know their names after all, but to most owners it seemed obvious.
