They were brother and sister. I remember a couple of litters of kittens while growing up.
The were born in MI and moved to CA in 1963. They lived a long time.
Our bedrooms were on 2nd floor, a tri-level.
My grandmother would babysit but was hard of hearing. One of them would go down to her, sit in front of her till she followed it up stairs to the correct room.
My aunt disliked cats. They would sit on the arms of the chair or couch she was sitting in and slowly move closer to her till she moved to another spot. I was 10 or 11 do old enough to watch and know what they were doing.
They would just quietly sit and stare at her. Lol. It was pretty amazing really.
