How do your cats react when you say their names/call them? Do they actually come to you?
Neither of our cats come when called (I wish!), even if we are right next to them and they're looking right at us. They only come when called if they can tell we're calling from the kitchen.
Lily used to meow when we would say her name, but I think at some point she realized she was giving us exactly what we wanted (which will NEVER do!), so now she does it sometimes, when she's in the mood, to prove that she is still in control.
Usually, when one of us calls her name, she'll twitch her ears towards that direction, and I suppose she expects we should be grateful for that small acknowledgement!
Sometimes she even does us the honor of TURNING and LOOKING at us when we call her name, before turning around again and resuming her activity.
Spencer pretty much ignores his own name - he does look at us in response, so I know he KNOWS his name - but he pretty much ignores EVERYTHING unless there is food involved. haha!
