I've found that a lot of cats do know their name, they just don't care that you called them. "Yes? Can I help you?"

It reminds me of I think Trade Wars when you'd try and land on a planet when you didn't have anything to sell that they were buying or any money to buy anything and the game refused, having the planet saying like "You have nothing I need and cannot buy anything I sell" - or something like that. Cat saying "Yes? Can I help you? You have neither treats nor toys and are wasting my time talking to me while I'm here, comfortable and happy. Away with you! Go and bother someone else." lol
