I’m sitting on my deck.
As I look at the sliding glass door I see my cat inside the house sitting in front of the door.
So I get up to open the door and let him out.
But once the door is open he just sits there and I’m left holding the door. He sits, he deliberates, sniffs the air and then he finally walks out.
Fast forward ten minutes.
The cat is back at the door. This time on the outside looking in. I get up to open the door.
When the door is open again the cat sits there, sniffs the doorframe and then looks up at me as if to say “why did you open the door?”
He turns away from the door and back onto the deck to do important cat things.
Fast forward three minutes.
The cat is back at the door. Once again I get back up and open it.
This time after a few sniffs and a few looks the cat walks inside. I sit back down.
Fast forward a minute and a half later.
The cat is back at the door.
And I don’t get back up to open the door. (I finally learn my lesson.)
It’s not that the cat wants the door open so he can go in or out.
The cat wants the door open so that he can have the possibility of going in or out, whenever he wants to.
