I have no idea how many times Sib and I heard that growing up. We’d hesitate in the middle of the doorway, either looking at something or trying to make up our mind if we wanted to go out or stay out or come in, and MomRed’s voice would echo down the hallway, ‘Go or come. Don’t be a cat in the doorway!” We heard it almost as often as “Close the icebox door! You’re letting all the cold air out.”
This is why the house cat shuffle was developed. It is not a dance step. It is a tool of self-preservation. Athena loves to sleep in the doorway. The doorway to the bathroom. She is very hard to see in the dark, say at 0330. And it is my fault if I step on or kick her.
MomRed just points and laughs.
