Selective hearing
My hooman is loud. I know he likes to talk to me in a high-pitched, squeaky voice. I'm not sure why hoomans do this - it's annoying. Where I can, I ignore him. I is too busy cleaning my feets, chasing dust, or napping. If I needs food or fuss, then I sometimes listen. But if he's simply calling my name across our home, then I generally ignore him. It's not worth twisting my ears round for. Too much effort. I like them to stay as neat, forward-facing triangles. If I hear a packet of food open, or my hooman comes home, or someone is talking outside, or I can hear a bird...then it's worth twisting my ears. Other than that, they stay in the one position.
