Roland will sit up on our bed, like a dog in 'begging' position, and flap his front paws at the ceiling fan. He only has one eye, and that eye has a bad corneal scar, so I think he is just chasing barely seen movement.

Precious, who has no eyes, always insists upon climbing to the highest possible point in any room she's in.

Timmy is cerebellar and can barely walk. Yet if I don't latch the door to the cat room he'll pry it open, tumble down to the living room and loudly brag about his accomplishment. He'll keep yelling until one of us returns him to the safety of his room.
