Cats ear position

I'm wondering if anyone elses cat does this.

Of course it's recognizable a cat is angry, scared etc if they put their ears back.

But roland does this thing sometimes where he lays his ears kinda sideways on his head, flat against his skull.

He does this when he's supremely relaxed and cuddling with me.. He's obviously delirious with joy at these times.

It makes him look like a very young kitten, before their ears pop up.
